Method -thresh2 has arg named 'function', but doc has 'argument:: thresh'.

WARNING: SCDoc: In /Applications/SuperCollider 3.13.0/SuperCollider.app/Contents/Resources/HelpSource/Classes/UGen.schelp
  Method -thresh2 has arg named 'function', but doc has 'argument:: thresh'.

This is a result of importing -thresh2 from SimpleNumber.

Relevant code for SimpleNumber:

• https://github.com/supercollider-quarks/MathLib/blob/master/HelpSource/Classes/SimpleNumber.ext.schelp#L11-L19
• https://github.com/supercollider-quarks/MathLib/blob/master/classes/SystemOverwrites/extSimpleNumber.sc#L4

... and UGen:

• https://github.com/supercollider-quarks/MathLib/blob/master/HelpSource/Classes/UGen.ext.schelp#L5C1-L5C35
• https://github.com/supercollider-quarks/MathLib/blob/master/classes/SystemOverwrites/extUGen.sc#L2

---

Suggested fix:

Update UGen.ext.schelp. Reference SimpleNumber:-thresh2, but refactor to use correct args. E.g., first arg should be named function rather than thresh.
