Support slash in UrlPath translations

We have a need to identify language in URLs.

This resembles adding /fr to the URL path of our french pages in the URL Segment of the French homepage and the UrlRoot (i.e Catalog_UrlRoot = fr/catalogue, Product_UrlRoot = fr/produit, Brand_UrlRoot = fr/marques)

Current setting does not support adding a slash (/) in the UrlPath translations, which is causing undesirable user experiences and language display issues.

Benefits to adding this feature:

SEO:

Search engines (like Google) can easily recognize language-specific content when it’s separated by a path (i.e., /fr for French). This helps with international SEO, making it easier to index and rank pages in the relevant language markets.

User Experience:

Users can easily identify the page's language by looking at the URL, which enhances usability and makes navigation more predictable, especially on multilingual sites.

If users share a link, the URL will immediately indicate the language, which is particularly helpful

Simplifies site structure:

A /fr structure keeps language variations in an organized hierarchy within the main domain, making it easier to manage language-specific content and maintain consistent tracking or analytics per language version.
