feature: allow to customise a Suffix for the exported assets

[carlosdevpereira]

Description

A common practise when naming components is to have a suffix specifying what type of component it represents. Example: CloseIcon.vue, UserIllustration.vue

This can also be useful if we are exporting the assets to a folder that has multiple types of assets and in the rest of our project we want to have a clear understanding of what components we are using.

Acceptance Criteria

• Add an input box to the plugin UI for the user to define a custom suffix that should be appended to the name of each asset being exported.
