What does this MR do?

Fix parsing errors of underscores in Maven versions.

0.0.62.Final-linux-x86_64
hadoop3-2.0.0
2.11.3-spark_3.3
3.4.0_1.4.2

Output of reference implementation:

1. 1_1 -> 1-_-1; tokens: [1, [_, [1]]]
   1_1 < 1_a
2. 1_a -> 1-_a; tokens: [1, [_a]]
   1_a > 1_
3. 1_ -> 1-_; tokens: [1, [_]]
   1_ < 1__
4. 1__ -> 1-__; tokens: [1, [__]]
   1__ > 1_-
5. 1_- -> 1-_; tokens: [1, [_]]
