Fix how path variables are escaped for Swagger

[AntoineJac]

changelog(Fixes): Fixed an issue where Path variables weren't properly escaped for Swagger specs

paths in swagger are not correctly escaped and won't be correct. You can try with following swagger:

openapi: 3.0.0
info:
 title: SampleAPI
 version: "1.0"
tags:
  - description: Sample API
    name: Sample Echo API
paths:
  /healthcheck/$echo:
    get:
      parameters:
        - in: query
          name: message
          required: true
          schema:
            type: string
          description: The echo message
      responses:
        "200":
          description: An echo message.
      summary: Return a echo message.
      operationId: getEcho
      tags:
        - Generate echo message
  /batchs(Material='{Material}',Batch='{Batch}'):
    get:
      parameters:
        - in: path
          name: Material
          required: true
          schema:
            type: string
          description: The echo message
        - in: path
          name: Batch
          required: true
          schema:
            type: string
          description: The echo message
      responses:
        "200":

According to the internal slack thread, the translation of the following string should be,

Source:

/Batchs(Material=''{Material}'',Batch=''{Batch}''):

Expected:,

"/Batchs\(Material='(?<Material>[^\/]+)',Batch='(?<Batch>[^\/]+)'\)$"

Actual:,

"/Batchs\\(Material=''(?<Material>[^\\/]+)'',Batch=''(?<Batch>[^\\/]+)''\\)$"

@marckong this was an issue with the UI, I fixed it. Can you please review? Thanks

/Batchs(Material=''{Material}'',Batch=''{Batch}''):

Expected:,
"/Batchs\(Material='(?<Material>[^/]+)',Batch='(?<Batch>[^/]+)'\)$"

Actual:,
"/Batchs\(Material='(?<Material>[^/]+)',Batch='(?<Batch>[^/]+)'\)$"

I ran smoke test to spin up a Kong gateway and it seems to be fine.

Ran smoke tests with the link example as well

This change is minimal. I tested out all the examples except those that don't meet openapi spec requirements, which failed to generate deck (happen in the develop branch too)
