fix(manager/go): fix replace block regex

[PhilipAbed]

Changes

changed the regex so it would support comment lines inside replace block

Context

• Closes go.sum update fails if go.mod contains a comment with a version #15369

Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please tick one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or
• No unit tests but ran on a real repository, or
• Both unit tests + ran on a real repository

needs test and regex is bad, see codeql error

[PhilipAbed]

• The Replace is being changed just so we could run the Command go get -t ./...,
  i added another replace section in the tests, the tests won't fail anyway because it doesn't change the final result
  there's no test i can add that can test the private function unless we use some reflection which isn't best practice..

• The regex replace\s*\((?:(?:\s*\/\/.*)?(?:[^)])?)+\)
  is meant to find replace keyword+ spaces + ( everything that is not end bracket[^)]+ except (?:\s*\/\/.*)? commented line )
  i read some documentation about this issue, but i'm not that familiar with regex, i'm not sure how to rewrite my regex in a better way, can you help?

Did you real run against a test repo with latest changes?

[PhilipAbed]

Yes, i ran it on this: https://github.com/StinkyLord/15369-go-get-failed

[viceice]

Very hacky, but i don't have a beter solution. Everyone should prefer to use gomodNoMassage
