mode naming

[zzkt]

https://github.com/k1LoW/emacs-ansible/blob/d89ac0ee57742cca0f0e0a3453d9dcc521575690/ansible.el#L276

is there a specific reason this is defined as ansible rather than ansible-mode?

adding the -mode suffix enables it to be used by other modes that assume standard naming (for example ansbile src blocks in org-mode via ob-ansible)
