• Closes Update to STAC API v1.0.0 🎉  #566

Description:

I've updated the core versions to v1.0.0, and each extension version to its latest. I've also updated the docs to point to the new extension locations after the breakout from the main repo.

To check validity, I spun up a stac-fastapi-pgstac instance that included this branch. I also had to use a patched version of stac-api-validator because of stac-utils/stac-api-validator#365. Before this PR, stac-api-validator reports:

INFO:stac_api_validator.validations:Validating STAC API - Core conformance class.
INFO:stac_api_validator.validations:Validating STAC API - Collections conformance class.
INFO:stac_api_validator.validations:Validating STAC API - Features conformance class.
Warnings:

- STAC API Specification <https://api.stacspec.org/v1.0.0/> is the latest version, but API advertises an older version or older versions.
