--prerelease does not work on build.gradle

[mnorlin]

Describe the bug
The version is not updated in build.gradle when using the --prerelease flag.

Current behavior

When executing

commit-and-tag-version --packageFiles build.gradle --bumpFiles build.gradle --prerelease SNAPSHOT

the version inside build.gradle is not updated.

The terminal outputs

Failed to read the version field in your gradle file - is it present?
✔ outputting changes to CHANGELOG.md
✔ committing CHANGELOG.md
✔ tagging release v0.0.4-SNAPSHOT.0
ℹ Run `git push --follow-tags origin main` to publish

When running the same command without --prerelease

commit-and-tag-version --packageFiles build.gradle --bumpFiles build.gradle

The terminal outputs

✔ bumping version in build.gradle from 0.0.3 to 0.0.4
✔ outputting changes to CHANGELOG.md
✔ committing build.gradle and CHANGELOG.md
✔ tagging release v0.0.4
ℹ Run `git push --follow-tags origin main` to publish

And the version is correctly updated in build.gradle

Expected behavior
Before the command:

version = "0.0.3"

after the command:

version = "0.0.4-SNAPSHOT.0"

Environment

• commit-and-tag-version version(s): 12.5.0
• Node/npm version: v20.15.0
• OS: MacOS 14.5
