Don't output extra whitespace in YAML multiline (#993)

This resolves a particular issue with parsing YAML multiline, for example: ```yaml a: | multiline literal line 2 ``` The regex used would capture the amount of indentation in the third capture group and then use that as a kind of "status" to know which lines are part of the indented multiline. However, because its a captured group it has to be assigned a token which was `TextWhitespace`. This meant that the indentation was outputted after the multiline, technically it should be seen as an non-captured group, but then its no longer to refer to it in the regex. Therefore I've gone with the solution to add a new token, Ignore, which will not be emitted as a token in the iterator, which can safely be used to make use of capture groups but not have them show up in the output. ## Before ![image](https://github.com/user-attachments/assets/c29353c5-9e15-4f14-a733-57a60fb51910) ## After ![image](https://github.com/user-attachments/assets/57b5d129-a9d3-4b84-ae1f-dc05182b9ad3)
