Preview variables in command palette

[Taitava]

Currently, if a command contains a variable, the command palette shows the variable's name:

A preview feature could show the variable content before the command gets executed. In this example case, the date could be shown like this:

This feature could be turned off in the settings. It will be on by default.

Support for aliases: You could write variables in aliases too. They would have no practical change to how a command would be executed, but this way your alias can show all the variable values that the command is going to use. For example, the above mkdir {{date:YYYY-MM-DD}} command could have an alias like this: Create today's folder {{date:YYYY-MM-DD}}, which would show up in the command palette as Create today's folder 2021-09-07.
