add extension bcmath for 2nd factor authentication

[yankeguo]

GMP or bcmath is required when second factor authentication is enabled.

For more details:

Enabling FIDO2 seems ok, but when login in with FIDO2, an error occured, says 'GMP or bcmath is required`.

Can you post some logs that shows that it's needed ?

[williamdes]

Maybe this could be related to #416 and #417

@williamdes

I'm using phpmyadmin:5.2.1 from official docker repository and trying setting up FIDO2/Webauthn 2nd factor authentication with Safari Security Key and Apple iCloud Keychain.

Safari keep prompting for authentication while logging in, and never success, after I cancelled authentication, I found this error message.

I've tried building an image with bcmath installed, and things work again.

P.S.: If you want to reproduce this issue, please note that enabling FIDO2/Webauthn requires SSL to be properly configured.

And I see no message in stdout/stderr

417 seems to be related, but I'm not sure that fix will restore GMP or bcmath extension

Okay, thank you for the input. I will have a second try at this
