Support the semantic-release specification as an option when generating a semverbot config file with `sbot init`

[shiouen]

Following comments on a introductory Reddit post, people have shown enough interest in the option of generating a semverbot configuration file for the semantic-release specification. It might even be made default.

Topics to investigate:

• should semantic-release be used as default?
• should it be implemented as an option for the init command? e.g. sbot init -t, --template semantic-release

semantic-release makes use of Angular commit messages by default, so the issue title is slightly missleading.

sbot init -t angular totally works too and might be known by a wider public.
