Fix 'get_website_content' parameter handling and improve text cleanup

[mikahanninen]

Description

The get_website_content could be called without user_agent parameter or by setting its value to empty dictionary and these were not handled correctly by the action.

The response size of the same action could be considerable (unnecessarily) due to empty spaces and/or line breaks within text content.

• Improved text content cleanup for all text properties
• Fix how parameter user_agent is handled for the get_website_content action
• Set max timeout 5 seconds for waiting for networkidle, but continue actions regardless

How can (was) this tested?

Tested with Sema4.ai VSCode extension and with Sema4.ai Studio.

Screenshots (if needed)

I'm guessing you need to define it as an empty dict because using None will cause the action lint to fail?

[mikahanninen]

Yeah the LLM sent some calls to this action without user_agent which broke the param handling. This was the easiest way to fix it.

[mikahanninen]

With this set the model will request for random user agent.

I'm not a huge fan of having mutable defaults as function params but I see we never modify the dict so this should be fine
