Fix `query` in GET requests

[gadomski]

Related Issue(s):

• Closes #355

Description:

Fixes query in GET requests by stringifying the JSON dictionary. Note that (for the Planetary Computer at least) the query parameter cannot be url encoded. @philvarner do you think this is a server bug? If so I can open it on stac-fastapi.

PR Checklist:

• [x] Code is formatted
• [x] Tests pass
• [x] Changes are added to the CHANGELOG

The query value should be url encoded, so it's a bug if stac-fastapi isn't handling that correctly.

The query value should be url encoded, so it's a bug if stac-fastapi isn't handling that correctly.

I've opened https://github.com/stac-utils/stac-fastapi/pull/504 to fix, and added url encoding to this PR. However, this means that tests will be broken until the Planetary Computer picks up stac-utils/stac-fastapi#504. I think it's worth waiting to merge this PR until the Planetary Computer is fixed, since this isn't a critical fix.

Agree with waiting -- I only found it because I had a get endpoint that was proxying through a stac api request, and I just wanted to pass the parameters through to pystac-client needing to parse them, but that was easy enough to do.

Okay, I'm marking this ready to review. Even if the Planetary Computer doesn't support quoted dictionaries in GET requests, users can always use POST.
