[Bug]: gptstudio::gptstudio_sitrep() states failing to connect to Anthropic API when it is actually connected

[bio-info-guy]

Confirm setup

• [X] I have installed the development version of {gptstudio} (pak::pak("MichelNivard/gptstudio")) and tested if the problem remains.
• [X] I have installed the {reprex} and {sessioninfo} packages to be able to run this issue's code snippet pak::pak(c("reprex", "sessioninfo")).

What happened?

When i run the command gptstudio::gptstudio_sitrep(), it states that I failed to connect to the Anthropic API service. However, I can confirm that I am using my own API for anthropic. Upon a closer look, I believe that the check_api_connection_anthropic function checks for connecitivity by calling for claude-2.1, which requires a request url of: "https://api.anthropic.com/v1/complete" and not ""https://api.anthropic.com/v1/messages".
