Read version from properties file in increment-version workflow

[DavDo]

Jira issue:
https://glia.atlassian.net/browse/MOB-5436

What was solved?

The "Increment project version" Bitrise workflow (_increment_project_version) was failing: the Bitrise Gradle Mirrors init script (bitrise-build-cache CLI) pollutes stdout of every Gradle invocation, so ./gradlew -q printCurrentVersionName returned the mirror log lines along with the version. This produced an invalid branch name in the Create PR step and failed the build with fatal: 'project-version-increment/[Bitrise' is not a valid branch name.

Now the version is read directly from version.properties — the same file the workflow updates and commits — making the step immune to any Gradle stdout noise. Same fix as salemove/android-sdk#1073.

Additional info:

• Is the feature sufficiently tested? All tests fixed? Necessary unit, acceptance, snapshots added? Check that at least new public classes & methods are covered with unit tests — CI-only change, no SDK code touched; extraction verified locally against version.properties
• Did you add logging beneficial for troubleshooting of customer issues? — N/A, CI workflow change
• Did you add new logging? We would like the logging between platforms to be similar. Refer to Logging from Android SDKs → Things to consider for newly added logs in Confluence for more information. — N/A
