Use conventionalcommits preset with @semantic-release/commit-analyzer

[andylolz]

release-notes-generator uses conventionalcommits preset, but commit-analyzer doesn’t. This means changelogs and releases can end up out of sync.

For example, the following commit:

git commit -m 'feat!: do a major release'

…will generate a changelog like this:

### ⚠ BREAKING CHANGES

* do a major release

### Features

* do a major release

…but the commit-analyzer output is:

Analyzing commit: feat!: do a major release
The commit should not trigger a release

The expected output is:

Analyzing commit: feat!: do a major release
The release type for the commit is major
