Importing from OpenAPI v3 Paramters in Path should be optional be imported as prompt

[ddcruver]

I would like to be able to import a OpenAPI v3 schema and hit send and it have it prompt me for each parameter in the path instead of requiring it to be defined in the environment.

For example instead of this:
url: "{{ base_url }}/filter/{{ filterId }}/purge"

it could optionally generate:
url: "{{ base_url }}/filter/{% prompt 'filterId', '', '', '', false, false %}/purge"
