fix(ui-mode): format request body when headers are lower case (#32395)

Browse source 
Resolves https://github.com/microsoft/playwright/issues/32396

Currently, the request body is not formatted when content type header is
lower case (`content-type`). Even though the value is
`application/json`.

It happens because we are looking only for `Content-Type` header
ignoring headers that are lower case.
