Describe the problem you'd like to have solved

It seems that the newly added Passkeys in Auht0 (https://auth0.com/changelog#3CBET2mBWyqK0RS6poEJiC) is not supported by the provider.

From the Management API (https://auth0.com/docs/api/management/v2/connections/patch-connections-by-id) I get the response

`
authentication_methods {
passkey {
enabled = true
}
password {
enabled = true
}
}

passkey_options {
challenge_ui = "both"
local_enrollment_enabled = true
progressive_enrollment_enabled = true
}
`

In Terraform I get "Unsupported block type" when adding the block

Describe the ideal solution

Expand the Auth0 resource "auth0_connection" in the options block by

`authentication_methods {
passkey {
enable = true
}
password {
enable = true
}
}

passkey_options {
challenge_ui = "both" or "button" or "autofill"
local_enrollment_enabled = true
progressive_enrollment_enabled = true
}`
