Fix version normalization for Minecraft classic

[SpaceWalkerRS]

Currently in McVersionLookup, it checks if the version string starts with c0. and removes the leading c character. This leads to invalid semver as a version like c0.0.11a ends up being converted to 0.0.11.a. I added two new regex patterns and changed the normalization so it gives the following results:

• c0.0.11a -> 0.11.0
• c0.0.23a_01 -> 0.23.1
• c0.24_st_03 -> 0.24.3
• c0.25_05_st -> 0.25.5
• c0.29 -> 0.29.0
• c0.30-c -> 0.30.0

I opted to strip all non-digit characters (a used in early classic versions, the st used in survival test versions, and the s and c used in late classic versions) because none of them are used to denote that one version is later than another.
