maint: switch from `print -P %F{col-nr} to m {col-name}

[psprint]

The m function is automatically provided for the moment of loading/installing a plugin and it's the same as +zinit-message.

Description

Allow theming of bin-gem-node messages.

Motivation and Context

There is a problem because the color codes are currently hard-coded into bin-gem-node. With this patch, the messages will make use of +zinit-message theming.

Please use +zi-log instead of m. m gives developers no information about what it does.

@vladdoster I've switched to +zi-log. That said, it would be good to document m function. It's designed to be used in atclone/atpull ices, to maximally shorten the code entered into them.
