Remove user base dir paths from generated documentation

[mwbrooks]

The generated documentation includes the user path of the system that generated the docs. We should replace this with a placeholder, if possible.

The issue dates back to May 2022 and it's not something that requires an immediate fix.

Originally discovered in #1751 (comment).

The page URLs

Example:

• python-slack-sdk/docs/api-docs/slack_sdk/oauth/installation_store/index.html

  Line 347 in e4df183

  <span>(</span><span>*, base_dir: str = '/Users/kazuhiro.sera/.bolt-app-installation', historical_data_enabled: bool = True, client_id: Optional[str] = None, logger: logging.Logger = &lt;Logger slack_sdk.oauth.installation_store.file (WARNING)&gt;)</span>
