feat: Lua trigger getGlobal(Chat)Var (#810)

# PR Checklist
- [ ] Have you checked if it works normally in all models? *Ignore this
if it doesn't use models.*
- [x] Have you checked if it works normally in all web, local, and node
hosted versions? If it doesn't, have you blocked it in those versions?
- [x] Have you added type definitions?

# Description
Allow usage of {{getglobalvar::}} equivalent in Lua trigger script

Further on, setting the global variable is the next scope to be
implemented.
