[FEATURE] - configurable bump commit message

[oknozor]

Is your feature request related to a problem? Please describe.
When creating a bump, a version commit is created with the following format chore(version): 6.0.1, users might want to use a different format.

Describe the solution you'd like
The version commit should be configurable in cog.toml and support version dsl.

Example:

version_commit = """
release({{version_tag}}): Bumped version from {{latest}} to {{version}}

A commit body

foo #bar 
"""

Additionally we should be able to override version commit using the CLI.
Since its probably something people want to automate, we should be able to write
The whole conventional commit (summary, body and footer) without $EDITOR.

This imply adding several arguments to the bump command to construct the version commit message

• summary + scope: should be a single string input, ex: chore({{version}}): bump version
• body : a single multi-line string
• footers: an array of key value pair

Describe alternatives you've considered
Port the cog commit --edit flag to the bump command. This could be added as well but it's probably not as useful as having a dedicated flag since it requires manual editing.

Additional context
This was fist proposed as a single flag to override the version commit scope (see: #375) which is a good idea but does not cover all possible use cases.
