Allow translation of strings in `Docs/conf.py`

[StanFromIreland]

For example, the page title is set in the file:

cpython/Doc/conf.py

Line 292 in 20d5494

html_short_title = f'{release} Documentation'

This does not allow for it to be translated, therefore in a translation (e.g. Polish), the English is rendered:

Closing for now per rationale in PR.
