TLS_CERT and BASIC authType have been removed from SOL013 since ed351

During Release 3 discussion, SOL and SEC delegates agreed to remove/drop several authorization/authentication methods (HTTP Basic, based on TLS certificates) from SOL013 and to introduce OAUTH2_CLIENT_CERT authType (See e.g. https://www.etsi.org/deliver/etsi_gs/NFV-SOL/001_099/013/03.05.01_60/gs_NFV-SOL013v030501p.pdf clause 8.3.4). It is unclear why there are still the following enum values BASIC, OAUTH2_CLIENT_CREDENTIALS and TLS_CERT in e.g. https://forge.etsi.org/rep/nfv/SOL002-SOL003/-/blob/4.5.1-dev/src/SOL003/General_Definitions/SOL003_def.yaml#L1158

Potentially impacting several repositories/branches if issue confirmed.
