Points: Also support prefix increments

[Asartea]

Complete the following REQUIRED checkboxes:

• I have thoroughly read and understand The Odin Project Contributing Guide

• The title of this issue follows the command name: brief description of request format, e.g. /help: add optional @user parameter

The following checkbox is OPTIONAL:

• I would like to be assigned this issue to work on it

---

1. Description of the Feature Request:

Sometimes people use the wrong form of increment (++prefix rather than postfix++), when trying to give someone points, which doesn't work. It would be neat if this also worked

2. Acceptance Criteria:

• ++@example works the same as @example++

3. Additional Information:

That sounds cool, I'm not sure how much more complicated it will make the points regex

odin-bot-v2/botCommands/points.js

Line 111 in 3860977

`(?<!\\S)${userRegex}\\s?(${doublePointsPlusRegex}|${plusRegex}|${starRegex})(?!\\S)`,

@TheOdinProject/maintainers what do we think?

Instead of using each of the different points regex individually in the awardPoints.regex, we could create a new variable so that the "main" regex isn't as long:

const starRegex...
const plusRegex...
const doublePointsPlusRegex...

const givePointsRegex = `(${doublePointsPlusRegex}|${plusRegex}|${starRegex})`

Then just check whether for "userRegex followed by givePointsRegex | givePointsRegex followed by userRegex". Doesn't really make it less complicated, but maybe a little easier to read?

`(?<!\\S)(${userRegex}\\s?${givePointsRegex}|${givePointsRegex}\\s?${userRegex})(?!\\S)`

The above sounds very reasonable. I like the idea of supporting pre-increment.
