Could not create math.calc variable if modulo is used

[J0B10]

Confirm the following

• I use the latest release or dev-build. I also checked that this problem hasn't already been fixed in a newer dev-build.
• There are no open or closed issues that are related to my problem.

BetonQuest version information

BetonQuest version: 2.0.0-DEV-754
Server version: git-Paper-196 (MC: 1.20.1)

Hooked into: Citizens (2.0.32-SNAPSHOT (build 3208)), ProtocolLib (5.1.1-SNAPSHOT-673), WorldEdit (7.2.17+6544-56d0383)

Expected behaviour

Math variable should resolve perfectly fine when used, even for modulo operator %, as written in the docs.

Given the following example:

events:
  test: 'log You clearly are a %math.calc:64%32% out of 10.'

Should resolve to: You clearly are a 0 out of 10.'

Actual behaviour

Resolves to: You clearly are a 6432% out of 10.'

Steps to reproduce

events:
  test: 'log You clearly are a %math.calc:64%32% out of 10.'

1. use above config
2. run /q reload
3. run event for a player

The following Regex is used for detecting variables:

BetonQuest/src/main/java/org/betonquest/betonquest/BetonQuest.java

Line 642 in 2fde85a

final Matcher matcher = Pattern.compile("%[^ %\\s]+%").matcher(text);

Thats why variables may not contain the % character.
