[REQUEST] output URL to report on codecov.io

[2bndy5]

Recent updates to zizmor have flagged my use of secrets.CODECOV_TOKEN as a rule violation (see secrets-outside-env). The remedy is to isolate any job that uses a secret to a protected environment.

This got me thinking. Github Actions environments support a URL that can be displayed on job success (see github docs). For a visual example:

So, if this action had an output of the URL that pointed to the corresponding project on app.codecov.io, that would be another way (beside a README badge) of navigating to the codecov project from github.com

Alternatively, the URL could be hard-coded:

    environment:
      name: test-coverage
      url: https://app.codecov.io/gh/cpp-linter/cpp-linter-rs

But having it set to something more dynamic allows for easy migration from an old code owner to a new code owner.
