fix(reana-dev): use chore commit scope when bumping dependencies (#868)

For commits created by `reana-dev git-upgrade-shared-modules` and
`reana-dev git-upgrade-requirements` commands, use "chore" rather than
"build" conventional commit scope, so that these commits won't appear in
the release news message.

The bug fixes or new features that are brought by upgrades are announced
in the release news in another way, such as when a feature needs the new
shared package or an upgraded version of dependency. The pre-release
version bumps can therefore go without a release news item.
