feat: decouple LtiConsumerXBlock.location from LTI 1.3 views

This commit upgrades the version of the lti-consumer-xblock library from version 4.5.0 to version 5.0.0. This new version contains breaking changes to the public Python API published by the library, but it mainly contains code refactors that decouple the LtiConsumerXBlock.location field from the basic LTI 1.3 launches.

LTI 1.3 launches should continue to work unaltered.

The only course staff or instructor facing changes are described below. The access token and keyset URLs displayed in Studio have changed in format.

The old format was:

Access Token URL: https://courses.edx.org/api/lti_consumer/v1/token/block-v1:edX+999+2022Q3+type@lti_consumer+block@714c10a5e4df452da9d058788acb56be
Keyset URL: https://courses.edx.org/api/lti_consumer/v1/public_keysets/block-v1:edX+999+2022Q3+type@lti_consumer+block@714c10a5e4df452da9d058788acb56be

The new format is:

Access Token URL: https://courses.edx.org/api/lti_consumer/v1/token/c3f6af60-dbf2-4f85-8974-4ff870068d43
Keyset URL: https://courses.edx.org/api/lti_consumer/v1/public_keysets/c3f6af60-dbf2-4f85-8974-4ff870068d43

The difference is in the slug at the end of the URL. In the old format, the slug was the UsageKey of the XBlock associated with the LTI integration. In the new format, the slug is the config_id of the LtiConfiguration associated with the LTI integration. This is an iterative step toward decoupling the access_token_endpoint and the public_keyset_endpoint views from the XBlock location field. The XBlock location field appears as the usage_key parameter to both views. We cannot simply remove the usage_key parameter from the views, because existing LTI 1.3 integrations may have been created using the old format, and we need to maintain backwards compatibility. This change, however, prevents new integrations from being created that are coupled to the XBlock. In the future, we may address integrations that use the old format to fully decouple the XBlock from the views.
