Use bot that automatically bumps versions

[jonahgraham]

@HannesWell created a bot that does that automatically for platform. Maybe you would like to adapt it for cdt too. https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/blob/master/.github/workflows/checkVersions.yml

If you can run CDT's maven build with a simple mvn verify it shouldn't be a problem to re-use it:
https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/blob/05d5c80188cc061c9a22b3b1cc86307686371009/.github/workflows/checkVersions.yml#L45-L47

See for example the PR in PDE how this can be set up:
eclipse-pde/eclipse.pde#1408

The biggest task is then probably to get the Personal Access token from the EF infra team:

• https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/5020

If you ask for that you can also ask for a nice profile picture for the bot like in

• https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/5043

And be careful to select the correct mail address of the bot to built the connection right:
