Docs/Governance: Add closing of abandoned PRs to responsibilities of the the triage role

[matkoniecz]

Description, Motivation & Context

I think it would make sense for Triage role to be allowed to close PRs which got abandoned. Or duplicated ones.

Note: it is already technically possible for them to do, they have "close" button active also on PRs.

Note: it is deliberate that "I think that this tagging idea is terrible" is omitted as reason for PR closing here.

Disclaimer: I just got triage role.

Looks good to me, and is also something I'd expect from the "triage" role. What do you think @tordans, @k-yle?

I am also willing to be convinced on including this as valid reason for PR closing for people in triage role. Unsure whether it should be done this way or not.

I think this is a good addition.
Here is one unrelated change suggestion – to update the docs to our current stack.
And one related change suggestion – to keep the wording of the paragraphs more similar in the way the are worded and structured.

@matkoniecz are you happy with my suggested changes? If so I think we could merge this…

[matkoniecz]

I merged subPRs

[tordans]

@matkoniecz thanks. Btw, what role do you yourself have now. Could you create a PR to add you to the docs?
