MegaMek 0.51.00, bash startup scripts

[worldly swan]

Well, partially a bug report I keep forgetting to submit:
add cd $APP_HOME to the next to last line of each bash startup script. I run these out of $PATH so having it assume I started from the base MekHQ directory is a bother and I've just been adding that myself every release.

Second... well, very little go on here:

Nobara is a lightly customized Fedora 43.  The Java is, as seen above, the base stock Java release though.
```cat /etc/redhat-release
Nobara release 43 (Forty Three)```

I'm running wayland but due to high DPI display I actually launch a pre-scaled Xwayland instance and run it inside of there. I tried it outside of that (rootless system Xwayland). My hardware doesn't work under native Xorg though or I'd test that.

@vital musk sorry for the ping, is this something you're familiar with?

[vital musk]

@worldly swan you need to install temurin Java, stock Java on fedora is headless these days

[worldly swan]

OH.

Well, thank you. :> Now I feel like a durp. Another reason for me to get off my rear and make a flatpak build pipeline.

I had this exact problem testing our release on Linux this morning
