chore: bump the version of fast-element to 3.0.0-rc.1 (#7499)

# Pull Request

## 📖 Description

Bumping the `@microsoft/fast-element` to version 3.0.0 release candidate 1 aka `3.0.0-rc.1`.

This is intended to showcase the updated APIs that were part of the now deprecated `@microsoft/fast-html` package and update the docs with sections on declarative template writing. This release candidate should include all breaking changes except #7247 which is currently being evaluated.

## 👩‍💻 Reviewer Notes

This change manually sets the version as beachball does not yet have a stable-to-prerelease and prerelease-to-stable feature.

We intend to publish several release candidates before moving to stable, which we will do as soon as we perform more testing and get community feedback on the updates.
