Subject: [PATCH] fix(compiler-cli): detect when the linker is working in
 unpublished angular and widen supported versions (#54439)

When the linker is running using an unpublished version of angular, locally built, the version will be `0.0.0`.
When encountering this situation, the range that for the linker map support is considered to be `*.*.*` allowing
for the linker to work at build time with packages built with versioned angular.

Most notably this allows for us to properly use the linker in building our documentation site with the locally
built version of angular.
