Bug: Regex Overmatches Sentry Key in URLs

The regex /sentry_key/ is too broad, matching "sentry_key" anywhere in the URL (path, fragment, parameter values) instead of specifically as a query parameter in the query string. This leads to false positives. A more precise regex, such as /[?&]sentry_key[=&]/, is needed to correctly identify Sentry ingest endpoints.

not sure if this is better, but we could also use parseStringToUrlObject here and compare the parts directly?
