Older documentation pages can cause confusion

[melissalinkert]

Prompted by https://forum.image.sc/t/extracting-metadata-from-cellsens-vsi-files/117574/3.

While our current RTD pages clearly warn if the latest version isn't being viewed (e. g. https://bio-formats.readthedocs.io/en/v7.3.1/), older pages that pre-date RTD and are not redirected have no such warning, e.g.:

• https://docs.openmicroscopy.org/omero/5.0.0/
• https://docs.openmicroscopy.org/bio-formats/6.0.0/

These pages still show up in search engine results, and can easily cause confusion around which version is the most recent. Is there any reasonable way to add some sort of banner to these pages that points to the latest/stable RTD page?

I wasn't exactly sure where to capture this issue, so happy to move or split this issue into different repos if needed.

To the best of my knowledge, these older doc pages are kept as static html only.
The overhead of designing such solution would be considerable.

Could we exclude these outdated pages from being indexed via robots.txt?
