Add an option to disregard trailing slash for automatic path tracking

[mathieumagalhaes]

Describe the feature or enhancement

I'd like something like data-exclude-hash=true but for trailing slashes.

What is this solving:

Umami currently showing /some-page-slug and /some-page-slug/ seperatly while this is the same page.
All statistics like visitors etc should be accumulated under one single slug.

Proposal:

data-exclude-trailing-slash=true
