The unbundled JavaFX versions (currently, 11 and later) in JBS follow the pattern "openjfxNN[.0.MM]". These JBS fix versions will be renamed to "jfxNN[.0.MM]".

For example:

openjfx20 --> jfx20
openjfx21 --> jfx21
openjfx17.0.7 --> jfx17.0.7
openjfx11.0.19 --> jfx11.0.19
...

We need to update the JBS version in .jcheck/conf in each active code line: jfx (mainline), jfx17u, jfx11u.

The planned cut-over date is Tuesday, Feb 28. I will prepare PRs for jfx:master, jfx:jfx20, jfx17u:master, and jfx11u:master to update the JBS version field in .jcheck/conf for all active code lines and integrate them immediately after the JBS version renaming is done.

Note that creating separate PRs targeted to jfx:master and jfx:jfx20 is a necessary exception to the usual rule where a fix goes into one or the other. In this case it needs to go into both so that they can be integrated immediately after the version change. The merge will have conflicts anyway, since the jbs fix versions are already different in the two branches, and doing it this way will allow a trivial resolution of the eventual merge conflict (which doesn't then have to be done urgently).
