Version 0.9.3 tag is placed before 0.9.3 version bump

This makes using a shard dependency inconsistent.

development_dependencies:
  webmock:
    github: manastech/webmock.cr
    release: 0.9.3

$ shards install
Updating https://github.com/manastech/webmock.cr.git
Installing webmock (0.9.3)
$ shards check
Dependencies aren't satisfied. Install them with 'shards install'
$ shards list
Shards installed:
  * webmock (0.9.2)

One workaround is to use the commit hash directly:

development_dependencies:
  webmock:
    github: manastech/webmock.cr
    commit: 8c1e360c80479f2708975334061c417332cbe89d

A better workaround would be to use the github tag at the correct location of the change.
