Clean up ai lab config

[tomuben]

Background

Some values of AI Lab Config are not needed anymore by the notebooks. We don't want to remove them from existing secret store instances, but can remove the entries in the AI Lab config Enum.

Candidates:

• slc_source
• slc_source
• slc_alias
• text_ai_pre_release_url
• text_ai_zip_password
• txaie_slc_file_local_path However, we also need to remove this reference:

  notebook-connector/exasol/nb_connector/text_ai_extension_wrapper.py

  Line 176 in e6bc11b

  If neither is given, checks if txaie_slc_file_local_path is set and installs this SLC if found,

Acceptance Criteria

Remove all listed entries from class AILabConfig.
