feature: allow to define variant properties to exclude from turning into props

[carlosdevpereira]

Description

Currently the plugin automatically checks which "variant properties" that each figma asset defines and tries to convert those variant properties into props (when generating Vue components). The only "hammered" exclusion for now is the variant property called "Name".

Acceptance Criteria

• Add a new form control to the plugin UI that allows the user to define a list of "Variant properties" he wants to exclude from turning into component properties.
  • By default the variant property called "Name" should be excluded

Implemented in b0d3054

Note: Instead of hammering a filter to exclude property "Name", the plugin is excluding every prop that does not have multiple possible values. This works in a "component based" approach and since "Name" in most scenarios does not have multiple possible values for the same component it get's excluded.
