PR template should be in imperative style

[l-emele]

Description of the issue

For the commits, we decided to use imperative commit messages.

With the PR you intend to change the dev branch (by merging the commits from your feature branch), that is conceptually also same, it is also a targeted action that you intend to do.

Therefore, I think we should also use the imperative convention for the pull requests.

Ideas of solution

Change section headings in the PR template:

• Added -> add
• Update -> update
• Removed -> remove

Workflow checklist

I opened this issue almost half a year ago. Nobody reacted to my proposal. Seems nobody except me has an opinion and especially nobody objects my proposal.

If in the next days nobody reacts I will implement as proposed.
