FindANTLR: Fix version RegEx

The currently used RegEx only allowed for single-digit version components for everything but the major version. Thus, when parsing e.g. the version 4.10.1, only the part 4.1 would be matched and thus, the determined ANTLR version would be wrong. Signed-off-by: Robert Adam <[email protected]>
