fix: additionally set electron user agent through CDP

[AtofStryker]

• Closes User agent in Electron isn't fully overridden when providing the experimentalModifyObstructiveThirdPartyCode option #23597

User facing changelog

Additionally overrides the electron user agent via CDP if the userAgent config option is provided or experimentalModifyObstructiveThirdPartyCode is enabled.

Additional details

It looks like the changes in #22958 did not fully override the electron user agent as expected (see #23597). In addition to setting the userAgent via the Electron's webContents.session API, we now optimistically set the user agent via CDP, which resolves the issue entirely.

Steps to test

How has the user experience changed?
