This PR

• adds .yamlld and .jsonld extensions

these should probably be classified as both their ld equivalents and the base config language as well in case one would want to lint those specifically

Hi @asottile! I landed here from pre-commit.

1. The desiderata is that jsonld and yamlld are at least linted with the JSON/yaml linters. It seems that check-yaml skips .yamlld files

2. It is possible to add further validation (eh using jsonld) JSON schema but it is a complex task to be achieved consistently.

How do you think it is possible to achieve point 1?

Have a nice day!

[asottile]

your patch does part 1 but you need to address my comment to get merged

PTAL I "copied" from the xhtml entry. Have a nice day, R.
