rust flatbuffers version upgrade

[cisaacson]

We are running Rust flatbuffers version 0.6.1, which is of course very old. We plan to update to the latest version 23.5.26. We have a lot of data we created with 0.6.1, I would expect that the binary format is the same and should work when we upgrade.

We will also update for other languages too, Typescript and Python. If they are all the same we expect that this will all work with our current data.

Please confirm if that is correct.
