DOCS-4129: Remove "Establish a connection" sections from API pages

[promptless]

Remove the "Establish a connection" sections from all API reference pages in /dev/reference/apis/ directory as requested by the user. These sections contain SDK connection setup, import statements, and basic configuration examples that are redundant with the CONNECT tab functionality and clutter the API reference documentation.

The sections to be removed typically include:

• Connection setup instructions referring to the CONNECT tab
• SDK import statements for Python, Go, TypeScript, etc.
• Basic client configuration examples
• Component/service naming examples

This cleanup will make the API reference pages more focused on the actual API methods and their documentation, while users can still access connection examples through the CONNECT tab in the web interface.

Trigger Events

• Internal discussion about removing "Establish a connection" sections from API reference documentation pages.
