ACS-4456 Add reusable workflow for basic Maven build and release

[dsibilio]

Adding a reusable workflow to match the most common Travis workflow we have at the moment, which seems to simply be build (sometimes with tests) -> release.

Example of usage: https://github.com/Alfresco/alfresco-tas-ftp-test/actions/runs/4016617042

Note: this is a work in progress, and will be merged only once most if not all repositories that should use such a basic workflow have been tested and therefore the workflow has become at least abstract enough to be utilized properly within all ACS repositories with similar, simple workflows.

Added some changes to make the workflow more generic, by allowing the consumer of the workflow to specify if they want the release to be happening automatically or manually induced via [release] commit trigger. Furthermore enabled the consumer to specify the release_branches regex to match all the branches that should be allowed to release the given repository.

Tests I've run with several input permutations:

Test #1 default input: https://github.com/Alfresco/alfresco-tas-email/actions/runs/4065941509/jobs/7001345703
Test #2 [no-release] + auto-release=true: https://github.com/Alfresco/alfresco-tas-email/actions/runs/4065913993/jobs/7001281611
Test #3 wrong release_branches: https://github.com/Alfresco/alfresco-tas-email/actions/runs/4065977169/jobs/7001427598
Test #4 auto-release=false: https://github.com/Alfresco/alfresco-tas-email/actions/runs/4065999192/jobs/7001480858
Test #5 [release] + auto-release=false: https://github.com/Alfresco/alfresco-tas-email/actions/runs/4066014703/jobs/7001513520
Test #6 [release] + auto-release=false + wrong release_branches: https://github.com/Alfresco/alfresco-tas-email/actions/runs/4066035998/jobs/7001565035
