LOVE: `love.filesystem.load` should be treated like `loadfile`.

I have a suggestion, hence the blank issue. When user set their environment as LOVE, love.filesystem.load should be added as loadfile equivalent in Lua.runtime.special in VS code.

Thank you for this awesome plugin, people who used it in LOVE Discord have good feedback with this plugin.

EDIT: Oh for additional context, in upcoming major LOVE version, we're adding 2nd parameter mode to love.filesystem.load which behaves same as mode parameter in Lua 5.3 load. Not sure how would Lua.runtime.special accomodate in that case though.
