[seo-check]: Exclude email links from trailing slash rule

[flauc]

Should email links be excluded from the trailing slash check?
'Internal links should include a trailing slash: [support@glycanage.com](mailto:support@glycanage.com) does not.'

[flauc]

This one is an error as well right?
'Internal links should include a trailing slash: [\n Start your wellness journey](/price-and-plans/?ref=home) does not.'
