[5.x] Remove _method in UpdateProfileInformationForm.vue

[osbre]

Makes it a bit simpler. I assume the _method property was used when there were no other ways to submit the form.

Also, this is the only place with _method in Jetstream and Breeze.

Hmm, not sure we should change this without full understanding of why it was historically done.

You're 100% right 😅 I just checked the docs:

Uploading files via put or patch is not supported in Laravel. Instead, make the request via post, including a _method field set to put or patch. This is called form method spoofing.
