Repository: storybook
Issue: [Bug]: Stories can't be found when CWD is nested within a complex directory structure
Labels: bug,help wanted,has workaround,core,sev:S3

### Describe the bug

### Setup

In a monorepo:

1. Storybook configuration in the root
2. Multiple packages, with stories in them
3. Storybook is not started from root, but rather from one of the packages - like a "core" package - and the `--config-dir` flag pointing up to the directory in the root.*

With a `stories` glob that is like this: `'../packages/@(core|other)/src/**/*.stories.@(js|jsx|ts|tsx)'`.

\* __Why not just start Storybook from the root?__
Svelte-Vite/SvelteKit setups require that `svelte.config.js` are in CWD (This is a Svelte requirement, nothing related to Storybook), and if those configs live in each package, you have to start Storybook from a package for Svelte to pick up that config. There might be other reasons too.

This setup was discovered when doing 7.0 QA on [the SvelteUI repo](https://github.com/svelteuidev/svelteui). 

### The bug

The sidebar fails to load with an error when indexing the stories:

```
Unable to index files:
- ./src/stories/Introduction.mdx: Cannot read properties of undefined (reading 'toLowerCase')
- ./src/stories/Button.stories.js: Cannot read properties of undefined (reading 'toLowerCase')
- ./src/stories/Header.stories.js: Cannot read properties of undefined (reading 'toLowerCase')
- ./src/stories/Page.stories.js: Cannot read properties of undefined (reading 'toLowerCase')
```

The problem is that each story's `importPathMatcher` is a regex that is supposed to be relative to CWD, but based on the `stories` glob. But if the glob cannot easily be converted to a relative CWD dir - because of the `@(core|other)` part - it won't be relative to CWD, and then it won't match the story file name that _is_ relative to CWD.
Here's what a `console.log` at `userOrAutoTitleFromSpecifier ` https://github.com/storybookjs/storybook/blob/next/code/lib/preview-api/src/modules/store/autoTitle.ts#L66 looks like for a failing story:
```js
{
  normalizedFileName: './src/stories/Button.stories.js',
  directory: '..',
  importPathMatcher: /^(?:\.\.\/(core|other)\/src(?:\/(?!\.)(?:(?:(?!(?:^|\/)\.).)*?)\/|\/|$)(?!\.)(?=.)[^/]*?\.stories\.(js|jsx|ts|tsx))$/,
  titlePrefix: '',
  userTitle: 'Button',
  fileName: './src/stories/Button.stories.js'
}
```

With the workaround below applied, here's what a similar `console.log` of a successful case looks like:

```js
{
  normalizedFileName: './src/stories/Button.stories.js',
  directory: './src',
  importPathMatcher: /^\.[\\/](?:src(?:\/(?!\.)(?:(?:(?!(?:^|\/)\.).)*?)\/|\/|$)(?!\.)(?=.)[^/]*?\.stories\.(js|jsx|ts|tsx))$/,
  titlePrefix: '',
  userTitle: 'Button',
  fileName: './src/stories/Button.stories.js'
}
```

That regex __does__ match the `fileName`.


### To Reproduce

1. Open reproduction at: https://stackblitz.com/edit/github-1xafeq?file=package.json
2. Start storybook with `yarn storybook` (which changes CWD to `packages/core`)

### System

_No response_

### Additional context


I believe the logic that fails to take this whole edge case into account lives somewhere in `normalizeStoriesEntry`.
https://github.com/storybookjs/storybook/blob/next/code/lib/core-common/src/utils/normalize-stories.ts#L34

There are a lot of pieces that makes this bug appear, so I would consider this a very edgy edge-case.

#### Workaround

If the stories glob is changed:

from
```js
['../packages/@(core|other)/src/**/*.stories.@(js|jsx|ts|tsx)']
```

to
```js
[
  '../packages/core/src/**/*.stories.@(js|jsx|ts|tsx)',
  '../packages/other/src/**/*.stories.@(js|jsx|ts|tsx)'
]
```
The "stories glob to CWD relative regex"-logic works.
