feat: add json output mode to reviews

[quotidian-ennui]

Motivation

Pipe chaining because we want oneliner coolness:

gh my reviews | grep "bump pre-commit" | awk '{ print $9 }' \
  | xargs -L 1 gh pr view --comments | grep "Terraform Plan"

The awk { print $9 } could be be brittle since you are relying on dependabot's commit message to only have a certain number of spaces (deps: bump x from 1.2.3 to 2.3.4 == 7 fields) along with the initial field being PR number at the start.

Making a JSON variant means that we could do this which doesn't change the semantics but enables us to be less brittle.

gh my reviews | grep "bump pre-commit" | jq -c -r '.url' \
| xargs -L 1 gh pr view --comments | grep "Terraform Plan"

Changes

• Introduce a -j flag to reviews (which could be added to other subcommands)
• -j forces --jq execution rather than --template (they are mutually exclusive)

Test

bsh ❯ ./gh-my reviews -j
{"login":"qe-repo-updater","number":75,"title":"chore(deps): Bump orhun/git-cliff version to v2.0.4","url":"https://github.com/quotidian-ennui/ubuntu-dpm/pull/75"}
