Make NSMBot commit message human-readable

[denis-tingaikin]

Motivation

Look at networkservicemesh/deployments-k8s#708 (comment)

As you can see commit message is not informative.

Potential solution

Each commit from NSM bot should link only to the previous PR (that triggered the current commit).

Tried some formatting changes for nsm bot message. Tested this on 4 repositories chain.
Result messages looks like this:

Link - Mixaster995/test-actions-4#22

Also made small fix for action retrieving pr number to work better.
I prepared changes for sdk repository: networkservicemesh/sdk#1041
and if it's ok, then i will made a batch of pr's for every repository.

@edwarnicke what do you think about this changes?
