Change Insomnia variables to path parameters in openapi import

[SpechtD]

Feature Request

With the introduction of path parameters in version 8.6 it would be more fitting to convert path parameters in openapi format to insomnia path parameters with a colon, instead of insomnia variables with double curly brackets.

Current behavior

openapi: /foo/{bar} insomnia: /foo/{{_.$1}}

Wanted behavior

openapi: /foo/{bar} insomnia: /foo/:bar

Affected code

https://github.com/Kong/insomnia/blob/0ddbccfd3e8d010d3b769a8e562325a8e27ac006/packages/insomnia/src/utils/importers/importers/openapi-3.ts#L272-L278

If my proposal is welcomed, I will open a PR with the requested change myself.

Colon led parameters would not be interpolated by nunjucks rendering. It uses brackets to identify syntax to evaluate.

I'm not sure if I'm overlooking something here, but after changing this path?.replace(VARIABLE_SEARCH_VALUE, '{{ _.$1 }}') ?? '';

to this path?.replace(VARIABLE_SEARCH_VALUE, ':$1') ?? '';

it works:

A setting to control the behavior would probably be quite suitable, if some people prefer the old behavior, but in my use case it would be a welcomed change.

I guess it's possible the question is can you make url and headers editable without causing bugs or side effects. @gatzjames what do you think?
