[PATCH yocto-autobuilder-helper] scripts/run-docs-build: make all versions list releases known to master

[Michael Opdenacker <michael.opdenacker@bootlin.com>]

This allows all versions of Bitbake and Yocto Project manuals
to see the manuals for the latest versions.

This also simplifies the release process, not having to update the
releases.rst file for all releases every time a new release is made.

Note that such synchronization is already done for the
switchers.js file (but in a different way). This way, advertised
releases are in sync with switchers.js.
