Does pgstac Query Extension support work with `neq` operator?

[philvarner]

I just filed https://github.com/stac-utils/stac-fastapi/issues/408 against stac-fastapi b/c the Query Extension "not equals" operator is incorrectly set to be ne instead of neq. This issue is to proactively ask if pgstac works with neq as the operator? I believe the current error I'm seeing is from the object validation within stac-fastapi, but once that's fixed, it may trigger a similar bug in pgstac, and I wanted to get ahead of that.

Judging from this migration it looks like it supports both.
