Should hopefully avoid weird broken link edge cases.
Relative links now trip up the Docusaurus broken link checker, so this
PR also removes them.
Also snuck in a small addition about asyncio
poetry can't reliably handle resolving the number of optional "extended
test" dependencies we have. If we instead just rely on pip to install
extended test deps in CI, this isn't an issue.
**Description**
The contributing docs lists a poetry command to install community for
dev work that includes a poetry group called `integration_tests`. This
is a mistake: the poetry group for integration tests is called
`test_integration`, not `integration_tests`. See here:
https://github.com/langchain-ai/langchain/blob/master/libs/community/pyproject.toml#L119
Builds out a developer documentation section in the docs
- Links it from contributing.md
