Twenty Twenty: add PHPDoc blocks for function action hooks

[viralsampat]

Hello Team,

I have reviewed the theme files and noticed the use of a PHPDoc block for the wp_body_open action hook in the TwentyTwenty theme.

I think that it should be appropriate, as it helps with documentation and clarity.

Thanks,
