[Bug]: Unable to use Ollama models: Error in validate_skeleton: api_key is not a valid character scalar. It is a <character>.

[indykpol]

Confirm setup

• I have installed the development version of {gptstudio} (pak::pak("MichelNivard/gptstudio")) and tested if the problem remains.
• 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?

This issue looks a bit different on the Github dev version from the CRAN version.

When I try to use chat with local Ollama host I get the following upon sending anything to the chat (after configuring the app to use local Ollama and selecting one of the available models):
Error in validate_skeleton: api_key is not a valid character scalar. It is a .
4: shiny::runApp
3: eval
2: eval
1: .rs.sourceWithProgress

I believe it pertains to the fact that:

1. new_gpstudio_request_skeleton has a validate_skeleton(url, api_key, model, prompt, history, stream) call
2. new_gptstudio_request_skeleton_ollama instantiates with api_key = "JUST A PLACEHOLDER"
3. It results wrong validation, despite a fact that vanilla Ollama doesn't use API keys at all
