feat(web): Add coordinate pair location searching. (#24799)

* feat(web): Add coordinate pair searching within the change location modal.

Adds simple logic to try and parse a coordinate pair in the format
`LATITUDE, LONGITUDE` as provided from Google Maps if a coordinate is
copied to update the coordinates automatically.

* Add checks for valid coordinate pairs

* Update formatting and fix linting issues
