chore(updatecli) Synchronize .ruby-version with updatecli and document version files (#8521)

* Synchronize .ruby-version with updatecli and document version files

- Add setRubyVersionFile target to updatecli/updatecli.d/ruby.yaml to track .ruby-version
- Update PR title to include .ruby-version in the automated bump
- Document .ruby-version and .node-version files in CONTRIBUTING.adoc

Fixes #8515 (PR 1)

* Fix .ruby-version matchpattern to exclude newline characters

Use '^[^\r\n]+' instead of '.*' to match only the version string
without the trailing newline, preventing duplicate lines in the file.

* Remove matchpattern/replacepattern as suggested by contributor

Following the contributor's suggestion, removed matchpattern and replacepattern
to let updatecli use its default behavior for single-line version files.
This should prevent duplicate lines issue shown in the dry run.

* Fix .ruby-version matchpattern to prevent duplicate lines

Use specific pattern to match version number only

* Remove matchpattern/replacepattern from .ruby-version target

Use updatecli default behavior for simple file replacement
