ci(): action permissions for PR from fork

[ShaMan123]

I read somewhere that PRs from forks receive a limited access token to avoid the fork accessing the repo.
This is why actions that do stuff like post a comment fail but there is a work around with tokens or permissions.

see romeovs/lcov-reporter-action#25

pull-request: write permission

Or generating an access token for PRs with the required permissions

[ShaMan123]

Needed for all actions that do something on the repo such as add a comment:

• build stats

Ok i think i found something, i have to generate a new token and for build stats instead we need to actually do some pass through of the token.
