Allow setting alpha value for ignorezero layer rule (#2477)

Browse source 
* rename ignorezero to ignorealpha

* allow setting ignorealpha value

This commit allows setting a float value (0-1) for the ignorealpha layer rule.
Does not yet have error handling; invalid ignorealpha layer rule will crash Hyprland.

* add brackets i forgot to add

* prevent crash with invalid ignorealpha value

prevents hyprland from immediately crashing with invalid ignorealpha layer rule
does not log

* don't try to set ignoreAlphaValue if alpha value not specified

* add catch to try, reintroduce ignorezero

- added catch after try cuz i was an idiot
- re-add ignorezero as an alternative to ignorealpha to not introduce a breaking change

* add logging for failed ignorealpha layer rule

* fix get ignorealpha's get VALUE

* check npos and use empty()

* rename VALUE cuz no longer const

* format Shader.hpp
