fix: DurationParser allowing invalid input

[emilyy-dev]

DurationParser using that regex and Matcher#find() only finds the pattern in the given input string, while the pattern is right for individual segments denoting value-unit sequences, it does not prevent the input to have non-matching content.
This patch fixes that by manually parsing the input.

Additionally it conforms to the recommended way of parsing an argument: peek input, pop input on successful parsing.

This isn't the case in 2.x, the tree will restore the cursor on a failed parse. You only need to do this if your parsing logic calls for it.

In that case the docs need updating 👍🏻 I'll revert that change here for now

Yes, the docs should be updated. When we switched over to the CommandInput there wasn't exactly a plan to no longer require peeking. That was introduced later on to increase the comfort of using the new system. I haven't done a thorough sweep of the documentation to reflect this (although it is at the very least pointed out in the external docs now)
