[BUG] [Go] api.mustache template change to use strings.replace for localVarPath not importing strings lib

Description

Modified api.mustache template to replace localVarPath. In files where strings package is not already present by default, generator is not importing the lib for strings causing compilation failure. Manually adding the imports causes duplicate import error.

openapi-generator version

4.3.1

OpenAPI declaration file content or url

https://gist.github.com/shylasrinivas/ba6cc06dbc5a731b00f5d06d0bb6d8ee
Line in api.mustache causing this issue -
localVarPath = strings.Replace(localVarPath, "__", "?" , -1)

Command line used for generation

openapi-generator generate -g go -p enumClassPrefix=true -p structPrefix=true -t ~/bindings/templates -i hcl.yaml -o ~/bindings/hcl

Suggest a fix

Used import alias functionality in go and added another import for strings Eg: strings and _strings. This fixes the compilation issue, however the code in the bindings does not look good.

Inspect the api.mustache template and the localVarPath strings.Replace line, then reproduce generation with the provided OpenAPI declaration and command. Confirm that generated Go files compile when strings was not previously imported and that existing strings imports do not become duplicates.
