is this also a liquid variable? or is it something else?

We should also add some docs around the liquid variable resolution functionality

[sid-acryl]

The parameter field, as described in the Looker documentation, is used to define variables accessible within Liquid templates using {% ... %} or {{ ... }} syntax. If no complex conditions need to be evaluated, these parameters can also be directly referenced in LookML views using the @{ ... } notation.

For example:

• sql_table_name: @{star_award_winner_year}
• sql_table_name: {% if user_attribute('use_schema') == 'true' %} {{ star_award_winner_year }} {% else %} public.winner_2024 {% endif %} ;;

The key difference between @{ ... } and using a Liquid template is that Liquid allows access to additional user-related attributes, while @{ ... } only references parameters defined in the parameter attribute of the view.

The attribute name liquid_variable in recipe is bit confusing. We can rename it to lookml_parameter, then it wouldn't convey the dynamic nature of liquid template. I can add additional documentation to liquid_variable or you can suggest some other name
