[Issue] Request-URL from OpenAPI import contains path parameter with curly brackets instead of colon

[chrisnagel]

Description

The import of an OpenAPI specification in YAML format leads to an incorrect transformation of path parameters.

An OpenAPI specification such as
/users/{id}

should normally read as follows in Bruno:
/users/:id

In fact, the imported request url contains the parameter specification in curly brackets (i.e. still in the form /users/{id}) and the parameter concerned is also listed in the Bruno GUI under Params/Path.
If the request is sent, the variable in the request url is not replaced.

.yaml file to reproduce the behaviour

openapi: 3.0.0
info:
  title: Sample API
  version: 0.1.9
servers:
  - url: http://api.example.com/v1
    description: Optional server description, e.g. Main (production) server
paths:
  
  /users/{id}:
    get:
      parameters:
        - in: path
          name: id
          required: true
          schema:
            type: array
            items:
              type: integer
            minItems: 1
          style: matrix
          explode: true
        - in: query
          name: metadata
          schema:
            type: boolean
          # Using the default serialization for query parameters:
          # style=form, explode=false, allowReserved=false
      responses:
        '200':
          description: A list of users
