Expected Behaviour

lua-language-server should create the cache directory on the user's home directory. On Linux this should be in ~/.cache/lua-language-server/ ideally.

Actual Behaviour

lua-language-server fails to start because it attempts to create the cache directory in a system directory which a regular user doesn't have permissions to write to.

Reproduction steps

1. Download lua-language-server-3.9.1-linux-x64.tar.gz and extract it to /opt/lua-language-server/
2. Make sure the owner of /opt/lua-language-server/ is root:root.
3. Execute /opt/lua-language-server/bin/lua-language-server --help
4. See error: lua-language-server: create_directories: "/opt/lua-language-server/log/cache/40815": (generic:13)Permission denied
