fix(compiler-cli): detect when the linker is working in unpublished angular and widen supported versions (#54439)

josephperrott · AndrewKushnir · commit da7fbb40f06e · 2024-02-14T15:43:22.000-08:00
When the linker is running using an unpublished version of angular, locally built, the version will be `0.0.0`.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. PR Close #54439
