Use Coroutine::list instead of Coroutine::listCoroutines (#294)

Update SwooleContextHandler.php (#209)
If the exception in the coroutine is not caught or other unknown circumstances, the code stack will run in a non-coroutine. At this time, Coroutine::getPcid($pcid) will return false, and SwooleContextHandler::isForked(int id) will raise a TypeError. fatal error

update readmes (#200)
Following on from Laravel's readme updates, apply the same to other readme files.
Add some badges, and a note to make clear that people are probably looking at a
read-only subtree split.
In passing, update wordpress dockerfile and metapackage to use RC

relax otel requirements, dont gitsplit tags (#93)
- relax composer requirements so that beta can be installed
- Symfony needs some attention to make it compatible with latest otel API/SDK > 0.0.15, so keep it at that version for now.
- dont gitsplit tags, we will do it manually for individual contrib modules post-split, since the contrib modules can be at vastly different stabilities
- fix up Dockerfile; the use of semi-colons meant that a docker build would happily continue past errors that weren't the last command in a step
