Allow conventional commits change scope to have spaces

[RobSmyth]

Is your feature request related to a problem? Please describe.
When add a new conventional commit change I cannot enter "convention commit" as the scope noun as the space breaks parsing.

This commit summary does not work:

feat(conventional commit): add scope noun to generated output

Describe the solution you'd like
Allow multi work change scope nouns.

Describe alternatives you've considered
Underscores or upper camel case would not appropriate as the scope noun is intended to appear in release notes.
