PHP Startup: Unable to load dynamic library 'gmp.so'

[nhymxu]

After fix GD library on #105

When using the newest image to run, I found another problem

<b>Warning</b>:  PHP Startup: Unable to load dynamic library 'gmp.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20220829/gmp.so (Error loading shared library libgmp.so.10: No such file or directory (needed by /usr/local/lib/php/extensions/no-debug-non-zts-20220829/gmp.so)), /usr/local/lib/php/extensions/no-debug-non-zts-20220829/gmp.so.so (Error loading shared library /usr/local/lib/php/extensions/no-debug-non-zts-20220829/gmp.so.so: No such file or directory)) in <b>Unknown</b> on line <b>0</b><br />

So I guess we need add gmp package to image too

https://pkgs.alpinelinux.org/packages?name=gmp&branch=edge&repo=&arch=&origin=&flagged=&maintainer=

It's second error report on #104
