Original GitHub issue: https://github.com/hoppscotch/hoppscotch/issues/5088

Is there an existing issue for this?

I have searched existing issues and this bug hasn't been reported yet

Current behavior

When I create a request with duplicate query parameter names, e.g.:

When I generate a curl request using 'show code', the request includes indexing, rather than just repeating the parameter:

curl --request GET \
  --url 'https://echo.hoppscotch.io/?test[0]=a&test[1]=b&test[2]=c'

Expected result would be to repeat the query parameter verbatim, not add indexing:

curl --request GET \
  --url 'https://echo.hoppscotch.io/?test=a&test=b&test=c'

Steps to reproduce

Enter a url into a get request
add query parameters in the 'parameters tab' with duplicate keys
on the send button, click the drop down arrow, choose 'show code'
choose 'shell - cURL'

I'd like to work on this. Planning to change the cURL generator to use repeated keys instead of indexed arrays. Let me know if that’s okay.

its happening because of http snippet's default behavior of indexing duplicate query params... will it be ok to replace it with a manually built cURL command?
