fix(login): Copy to clipboard button in MFA login step now compatible in non-chrome browser (#9880)

related to issue [#9379](https://github.com/zitadel/zitadel/issues/9379)

# Which Problems Are Solved

Copy to clipboard button was not compatible with Webkit/ Firefox
browsers.

# How the Problems Are Solved

The previous function used addEventListener without a callback function
as a second argument. I simply added the callback function and left
existing code intact to fix the bug.

# Additional Changes

Added `type=button` to prevent submitting the form when clicking the
button.

# Additional Context

none
