fix(installer/bootstrap): pin luarocks to v3.11.1

[mrcjkb]

Should hopefully fix #568.

@ambaradan would you mind testing with the changes in this PR? 🙏

I still have a RHEL at home; I will do some tests on that tonight to rule out any error on my part.

Same thing using luaver

stderr: /home/ambaradan/.luaver/lua/5.1/bin/lua: ...511A84450400/share/lua/5.1/luarocks/core/persist.lua:25: bad argument #1 to '
load' (function expected, got string)

🤔 I just tried running the install script (the one on master) on NixOS, and did not encounter any issues.

The stack trace in your screenshot is definitely for the current HEAD of the master branch of luarocks (load being called in the luarocks.core.persist module on line 25).
On the v3.11.1 tag, there's no load call on that line.

Merging this PR, as it makes sense to pin the version anyway.
After that, you can try again with the regular install script.

@mrcjkb The fix solved the problem, now the installation works again even on RHEL, many thanks.
