feat: check for email address in max-line-length

### Expected Behavior

"Co-Authored-By: my-really-long-email-address@my-really-long-domain.com" shouldn't trigger a body-max-line-length error.

### Current Behavior

It does.

### Affected packages

- [ ] cli
- [ ] core
- [ ] prompt
- [ ] config-angular

### Possible Solution

There seems to be a case where the length gets ignored when a URL is included in the line. Expand that to include an email or co-authored-by tag.

### Context

Copilot can be used to create a pull-request. It attributes your GitHub user as a co-author. This line can extend beyond normal length requirements.

Our current solution is to disable the line length check, but it would be nice if it recognized the tag line and ignored it.
