Update version detection for --legacy flag due to changes in xcresulttool version number

[stepheng]

Xcode 16: xcresulttool version 23024, format version 3.53 (current)
Xcode 26: xcresulttool version 24051.1, schema version: 0.1.0 (legacy commands format version: 3.53)

The regular expression added to determine if the --legacy parameter is needed only matched on numeric characters for the version, the new version number has a decimal and would result in a null pointer error being thrown when trying to get the version. Updated to optionally support the decimalised version number. If no match is found, assume it's a newer version and assume --legacy is needed in this case as well.

This is the trace seen when this issue this PR resolves is hit:

/Users/bamboo/.gem/gems/xcresult-0.2.2/lib/xcresult/parser.rb:90:in `xcresulttool_command': undefined method `[]' for nil:NilClass (NoMethodError)

What's the timeline on getting this merged? It may solve the following error I'm getting in Xcode 26.1. But not on 26.0 for some reason?
