Issue:
Styles flash when using CSS Modules in the development environment
### Describe the bug

Styles flash when using CSS Modules in the development environment .
I found that in inlineStyle, the style of CSS Module was not inserted correctly, and the [object object] was incorrectly spliced.

Pull request:
Avoid FOUC when using CSS modules in dev
Fixes #5019

Importing CSS modules causes flash of unstyled content, as an object is returned from Vite causing it to be injected as `[object Object]` inside the style tag.
Importing with `?inline`, allows Vite to returns the CSS  as string which can be used inside the style tag.

### Please don't delete this checklist! Before submitting the PR, please make sure you do the following:
- [x] It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
- [x] This message body should clearly illustrate what problems it solves.
- [ ] Ideally, include a test that fails without this PR but passes with it.

### Tests
- [ ] Run the tests with `pnpm test` and lint the project with `pnpm lint` and `pnpm check`

### Changesets
- [x] If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running `pnpm changeset` and following the prompts. Changesets that add features should be `minor` and those that fix bugs should be `patch`. Please prefix changeset messages with `feat:`, `fix:`, or `chore:`.
