Update gh (Github CLI) to 2.6.0.

GitHub CLI 2.6.0

Repo Search

@samcoe is working on a new command, gh search! In this release it's shipping
with just support for repository searching. Results can then be processed with
--jq or fillter columns with --json and filters are expressed with flags like
--topic or --license.

Try it out with something like: gh search repos --language=go
--good-first-issues=">=10"!

Rerun failed jobs

gh run rerun has been augmented with two new flags: --failed and --job by @cdb.
You can now selectively rerun just failed jobs from a given workflow run!
Running gh run rerun --failed will prompt you to select a run to work with.
