Fails with AWS CodeCommit repository URLs

The plugin fails if the git repository uses a "non-standard"git URL, e.g., AWS CodeCommit URLs:

codecommit::eu-central-1://<profile>@<repository name>

I turned link generation of, but the plugin tries to parse the URL anyway:

[15:26:27] [semantic-release] » i  Start step "generateNotes" of plugin "@semantic-release/release-notes-generator"
[15:26:27] [semantic-release] » ×  Failed step "generateNotes" of plugin "@semantic-release/release-notes-generator"

The fix seems to be to check the result of the match for null and assign the empty array.

Start in generateNotes in index.js and reproduce the failure with the AWS CodeCommit URL while link generation is disabled. Check the match result before it is iterated, then verify that generateNotes completes without the null-iteration error for this URL.
