WoS API REST Switchover Work

Once the new WoS REST based code is deployed in #1612:

[x] We should update wiki pages that reference the WoS querying code to match the new class/method names, so they continue to work.

Pages to check:

[x] https://github.com/sul-dlss/sul_pub/wiki/Useful-console-commands-(harvest,-WoS,-Pubmed,-others)
[x] https://github.com/sul-dlss/sul_pub/wiki/WOS-Author-Harvest-Design <-- candidate for removal instead of fixing DELETED
[x] Make a puppet PR to get rid of the WOS_AUTH_CODE environment variable. See https://github.com/sul-dlss/puppet/pull/9661 for where the new API key was added: https://github.com/sul-dlss/puppet/pull/9981
[x] Remove the WOS_AUTH_CODE values from Vault (locations shown in puppet) for all 4 environments (prod, stage, cap-dev, and qa)
