Request: use canonical Maj.Min.Patch form for tagging

[Gian Lorenzo Meocci]

Can you tag this lib using the canonical form:
Maj.Min.Patch

example:
0.9.9 instead of v0.9.9

thanks

@meox the hex convention defaults to prefix tags with a v. For the ex_docs plugin, it looks like it is configurable now: jelly-beam/rebar3_ex_doc#18
