feat!: compile to JS before publishing

[arbrandes]

Configure the package to compile TypeScript and copy SCSS files to dist/ before publishing, rather than publishing raw source files. This allows us to use tsc-alias for @src imports.

Also use a more modern export map to decouple the internal file structure from the package's API, and add a build step to CI.

BREAKING CHANGE

Consuming projects may need to update their imports or SASS @use lines.

Depends on

openedx/frontend-base#164

Overall this looks good, but the whole "make a temporary release" workflow seems like it has a lot of moving parts.

Personally I'd prefer to:

• Not make any temporary PR releases
• Run the package step on if: github.event_name == 'pull_request' (I think that's the simpler syntax)
• Use something like https://nightly.link/ to address the "it's annoying to dig through the build logs to find the artifact" issue

nightly.link even has an example workflow for leaving a comment on the PR with a link https://github.com/oprypin/nightly.link/blob/master/.github/workflows/pr-comment.yml

@brian-smith-tcril, I may have accidentally included the temporary release stuff in here, but it's completely separate now.

@brian-smith-tcril, missed a force-push, sorry. Should be good now.

LGTM!
