Pull request overview
This PR adds support for custom stderr handling in Bazelisk's Go library API, allowing library consumers to redirect stderr output to custom writers instead of always using the process's stderr. This enhancement improves the flexibility of Bazelisk when used as a library.
Changes:
- Added new public API function
RunBazeliskWithArgsFuncAndConfigAndOutAndErrthat accepts both stdout and stderr writers - Updated internal functions
makeBazelCmdandrunBazelto accept and handle custom stderr writers - Maintained backward compatibility by having existing functions delegate to the new function with
nilfor stderr

This allows library users to control what happens with stderr (e.g. write it to a file or buffer instead of the process' stderr).
