Fix double digits Ansible version match

[robinmulder]

Vagrant does an Ansible version check in the Ansible provisioner to determine which compatibility mode to use. The latest version of Ansible is Ansible 10 and this check fails in Vagrant when using Ansible 10.

% python3 -c "import importlib.metadata; print('ansible ' + importlib.metadata.version('ansible'))"
ansible 10.3.0

This is the first time that double digits are used in an Ansible major version. The regex that is used to determine the major version in Vagrant only checks a single digit. So in this case it matches to 0, which in turn will trigger compatibility mode 1.8 instead of 2.0. Compatibility mode 1.8 uses sudo in the command, instead of become which is needed by recent Ansible versions.

This PR updates the regex to check all digits before the first dot, so the major version is set to 10 instead of 0 and the correct compatibility mode is selected.
