Add repository-projects:read to release job token

After #470, the release GitHub Action workflow is failing to add labels
to PRs.

```
gh pr edit --add-label e2e-all-k8s \
submariner-io/submariner#2032
GraphQL: Your token has not been granted the required scopes to execute
this query. The 'login' field requires one of the following scopes:
['read:org'], but your token has only been granted the:
['admin:repo_hook', 'delete:packages', 'notifications', 'repo',
'workflow', 'write:discussion', 'write:packages'] scopes. Please modify
your token's scopes at: https://github.com/settings/tokens.
INFO: Didn't label 'e2e-all-k8s', continuing without it.
```

The only explination I can find of that permisson is:

> read:org Read org and team membership, read org projects

I can also see that permission is a subset of admin:org. It seems to be
different than `read:project Read access of projects` somehow.

It's not clear which GITHUB_TOKEN permisison we can set relates to those
token permissions.

docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs

It doesn't seem possible set all permissions to read and only some to
write, as setting any specific permission overrides read-all.

For now, trying the only permission that seems even vaguely related.
