feat: Expose axios interceptors

[artonge]

This eases requesting for password confirmation

Question would be:
Do we want to support both ways at the same time or only the new way in the future?

Because if we only use the new way in the future, then I think it would make more sense to provide a more convenient way to handle this.
Something like:

import axios from '@nextcloud/axios'
import { withPasswordConfirmation } from '@nextcloud/password-confirmation'

withPasswordConfirmation(axios).post('a/dangerous/route')

Where withPasswordConfirmation would add a once-time interceptor to the request that adds the password header.

What do you think?
