Remove trailing comments in parsed SBT module version

[aartigao]

At $work we recently noticed that Scala Steward was not updating dependencies that have trailing comments like

"software.amazon.awssdk"                 % "dynamodb"                     % V.aws, // Overrides `scanamo` version
"software.amazon.awssdk"                 % "sso"                          % V.aws, // Needed for local dev!
"software.amazon.awssdk"                 % "sts"                          % V.aws  // Needed for EKS IAM!

these we're workarounding them by placing the comments elsewhere:

// The following comments are not inlined to avoid breaking Scala Steward!
// - Module `dynamodb` overrides `scanamo` version
// - Module `sso` is needed for local development
// - Module `sts` is needed for EKS IAM
"software.amazon.awssdk" % "dynamodb" % V.aws,
"software.amazon.awssdk" % "sso"      % V.aws,
"software.amazon.awssdk" % "sts"      % V.aws

but I think this can be easily avoided by changing the regex like in this PR.

I don't have any idea if this impacts anything else in the code (tests are green at least locally), so let's discuss it because I think the current behavior is not the expected one 🙏🏽
