Lsp-mode: lsp-lua prevents lsp from starting on system without java

[ratking82]

Describe the bug
Lsp-Lua prevents lsp from starting when java is not present on the system. Removing lsp-lua from lsp-client-packages fixes the error.

To Reproduce
Try on a system where java is not installed. I donot have java on my system.

Expected behavior
Lsp to start when non lua buffers are opened.

Which Language Server did you use
lsp-python, lsp-clangd

OS
Ubuntu 20.04 lts, emacs 28.0.50

Thank you for the report. Sorry about that - apparently maintainers and CI have java.
