Our help-beta conversion script expects text to be indented if the text
is part of the same list item. If it is not part of the same list item,
then it expects an empty line just after the list item. This commit
fixes existing instances for the same by searching for regex: `^1\.
.*\n(?!\n)(?!1\.)( {0,1}\S.*)`.
We do not want to add a lint rule for this, since not indenting is not
technically wrong. We will add a TODO list item in the conversion script
for help-beta in future commits.
Updates `.md` files in api_docs/ to use "stream" instead of "channel"
for descriptive text, with the exception of the API changelog file.
Part of stream to channel rename project.
- Updates `.prettierignore` for the new directory.
- Updates any reference to the API documentation directory for

- Removes a reference link from `docs/documentation/api.md` that
hasn't referenced anything in the text since commit 0542c60.
- Update rendering of API documentation for new directory.
