Add interlock-cb to third-party libraries

[bagowix]

What do these changes do?

Adds interlock-cb to the third-party libraries page. I am the author of interlock-cb.

Are there changes in behavior for the user?

No aiohttp behavior changes. The documentation now points users to an aiohttp client circuit
breaker middleware that maintains one breaker per host and trips on failure rate or slow
responses.

Is it a substantial burden for the maintainers to support this?

No. This is a documentation-only entry for an independently maintained third-party library.

make doc: not run successfully because the existing local development environment is missing myst_parser

Have you tried reading the contrib doc tho?

[webknjaz]

FTR, there's now an ongoing incident w/ GHA, which is why some runners crash: https://www.githubstatus.com/incidents/qcvjkzcs7j74. The maintainers will need to restart the jobs once that outage is over.

[bagowix]

@webknjaz Thanks for the pointer! I followed the contributor setup instructions and ran make doc successfully. I’ve updated the PR description accordingly.
