feat(tikv,pingcap): add lint job for community repos (#3273)

This pull request includes updates to the `prow-jobs` configuration
files to add new presubmit jobs and refine existing configurations. The
most important changes include adding new presubmit job configurations
for `pingcap/community` and `tikv/community`, and refining branch
specifications for postsubmit jobs.

### Why

Some times the community maintainers contribute wrong format team
membership json files, It will make the bot(ti-chi-bot) can not work to
sync the OWNERS files for the controlled repositories. I made the pull
request to add basic json verify jobs for membership json files to block
wrong changes on format.

### New presubmit job configurations:

*
[`prow-jobs/pingcap/community/presubmits.yaml`](diffhunk://#diff-201e72a2e194854030a794a5b8bbf9cbf0464c4ea4dfc225871c70eb822a4f23R1-R25):
Added a new presubmit job `pull-verify` for `pingcap/community` to check
JSON files using `jq`.
*
[`prow-jobs/tikv/community/presubmits.yaml`](diffhunk://#diff-30ab0438808b8b152ea23af14f48aaa5ef79bcdb57e58c78fd96573a7f82246aR1-R25):
Added a new presubmit job `pull-verify` for `tikv/community` to check
JSON files using `jq`.
