[TS-607] Improvement - Check for identifiers since last tag

[zyexal]

Currently the minor-identifier or major-identifier is needed on the latest commit message to have any effect.

Scenario - Project with version 1.0.2:

• User is creating many commits on a branch
  • minor changes, improvements etc. with simple commit messages and
  • a new feature with commit message containing minor-identifier (used as minor version increase identifier)
  • also publishes/deploys snapshots to repo
• User creates a PR, but misses to add minor-identifier to the PR title

Outcome:

• Snapshot with version 1.1.0 as we had a commit message with minor-identifier
• Published 1.0.3 as minor-identifier was missing in the PR title

Improvement possible:

• Let user decide if a missing identifier shall
  • break the workflow exceptionally,
  • increase versions based on commit and PR title (latest commit) or
  • ignore older commit messages (current behaviour)
• Needs possibility to check all commits since the last tagged for minor-identifier or major-identifier
