fix(core): use toolTitle for document.title if present

[pedrobonamin]

Description

The browser <title> tag should use the tool's title field (if provided) rather than name

Sanity Studio is using the name field instead of the title field for the browser's <title> tag when working with tools. Additionally, the Studio is automatically transforming camelCase names into separate words, which produces incorrect results in Norwegian and probably other languages.
