Description:

The user can optionally provide a filter-lang parameter to the
ItemSearch endpoint when using filter. This preserves the existing
behavior of defaulting to cql-json when no value is provided, so it
should be backwards compatible with existing code. By optionally
providing a new value, such as cql2-json, the user can supply filters
with different JSON language variants.

This change minimally anticipates the forthcoming STAC-API beta release
of the filter fragment while preserving existing behavior. After the CQL2
changes are released in the next beta, it's likely we'll need a larger refactor
around supporting cql2-text, new conformance classes, etc. In the meantime,
this change will allow Planetary Computer users run cql2-json filters which are
supported in our pgstac implementation.

PR Checklist:

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