Allow to transform programatical to ESM remove circular dependencies @actions/core

Describe the enhancement
I need to Transform the code programatical to get useable analyseable static code that i can depend on.

Code Snippet
i think the api enhancment is clear every editor will show the correct types at last with my transpiled version

Additional information
I think no one would want to use this directly even if many people do it i am 100% sure they did never watch the code or did try to modify it.

This is the circular dependencie that blocks me partial the solution is clear to isolate the dependencies into the related files.

node_modules/@actions/core/lib/core.js -> node_modules/@actions/core/lib/oidc-utils.js -> node_modules/@actions/core/lib/core.js

i assign my self and will submit a PR i will also clean up this issue later i want now to directly jump into that

Update PR Done

There is now a PR #982 and even a small additional one that fixes a typescript type issue #983

Start by reviewing packages/core/src/core.ts, packages/core/src/oidc-utils.ts, and packages/core/src/utils.ts, which are named in the issue's proposed change and patch. Check whether the circular dependency is removed and the TypeScript package remains usable; the issue references PRs #982 and #983, so the work may already be complete.
