Support for the latest v23.1.21 version

[guenhter]

Hi,

would be nice to have support for the very latest version of flatbuffer.

Due to I'm new to flatbuffer and also to the way its compiler is built, am (not yet) able to contribute here too much (but maybe when in the future when I got how this works).

Ok, this works surprisingly easy. I think I never saw a docker image creation which was so well documented as yours and works so easy (I don't have to specify basically anything). Well done.

Could you maybe upload an image of the latest version?

Thanks for the compliment! =)
I'll see what the situation with the latest version numbers are and update the tags.

I hadn't noticed that the master branches haven't built in a long time... taking care of that, then this.

Alright, I'm working with Travis CI support to remedy this... I don't do my own builds + image pushes, but rather use public-facing CI/CD services so that the community can scrutinize the build logs.

OK, Travis CI fixed it quickly -- many thanks to them for the build minutes.

I just triggered a master build and it created tags like with the latest main from Flatbuffers and flatcc:

• clang-20230221
• gcc-20230221

Thank you very much for the extremely fast reaction time. Appreciate it.

I'd still like to make a recent versioned tag, but haven't circled back to this yet. So re-opening....
