as_type seems to be used incorrectly

[CasperWA]

In the test of as type, it seems we're passing the root base URL, which shouldn't be the case, right? We should pass in a full URL to a relevant single endpoint that should be validated using the passed type?

I.e., instead of testing:

TEST_BASE_RUN_VALIDATOR="optimade-validator $( for i in {1..${INPUT_VERBOSITY}}; do echo '-v '; done; )--as-type ${VALID_AS_TYPE_VALUE} ${INPUT_PROTOCOL}://${INPUT_DOMAIN}${INPUT_PATH}"

We should be testing:

TEST_BASE_RUN_VALIDATOR="optimade-validator $( for i in {1..${INPUT_VERBOSITY}}; do echo '-v '; done; )--as-type ${VALID_AS_TYPE_VALUE} ${INPUT_PROTOCOL}://${INPUT_DOMAIN}${INPUT_PATH}v1/structures/${VALID_STRUCTURE_ID}"

Where VALID_STRUCTURE_ID is a variable that ensures we are testing a valid structure ID.
Note, VALID_AS_TYPE_VALUE=structure here.

Essentially, the action should avoid adding versioned parts to the URL and simply use the passed path parameter as is.
