[BUG] generated operationId should not contain slash

[harish2704]

Describe the bug
In my understanding, operationId used openapi spec basically serves the purpose of a method name . If that is correct, it should not contain slash ( "/"). But currently, generated operationId will contain slash because it is derived from path used in the router. This slash can break generated HTML documentation ( it at-least breaks the html2 generator )

To Reproduce
Steps to reproduce the behavior:

• clone this repo https://git.harishk.in/harish2704/language-identification-api
• Run the server and download generated openapi.json file ( wget 'http://127.0.0.1:8000/apidoc/openapi.json' )
• Now generate html documentation from this spec ( openapi-generator-cli generate -i openapi.json -g html2 )
• Open the generated file in the browser, check the developer console, we can see many javascript errors. We can also see the following issues
  • we will not be able to switch tab in the generated client-side code section.
  • Syntax highlight didn't worked for generated code
  • Response schema was not displayed in the browser.

Expected behavior
Expecting a fully functional generated HTML file ( like this https://git.harishk.in/harish2704/language-identification-api/src/branch/main/generated/index.html ) But produced HTML was broken
