Issue:
intercept lifecycle for HTML based resource plugins not getting called during static compilation (when `prerender: false`)
## Type of Change
- [ ] New Feature Request
- [ ] Documentation / Website
- [ ] Improvement / Suggestion
- [x] Bug
- [ ] Other (please clarify below)

## Summary
As part of working on #855 , I noticed that the HTML Includes plugin was not running anymore and the [specs were failing unless I had `prerender: true` in my _greenwood.config.js_](https://github.com/ProjectEvergreen/greenwood/pull/857/files#diff-1e34476069d5db6d510e2561553c5c48ad4f9e0c2d7aa8d28563e8c807219d55R4).

## Details
The reason for this looks to be that for [static only build, Greenwood only serves, but never calls the `intercept` lifecycle](https://github.com/ProjectEvergreen/greenwood/blob/v0.21.0/packages/cli/src/lifecycles/prerender.js#L111), which means that the plugin will never get called.  This means that #846 would break too when merged and used in a similar scenario.

resolves #858 

## Summary of Changes
1. Added `intercept` logic to `staticCompilation` for when `prerender: false`
1. Covered with "forced" test case (will undo in #857 )
