bad generated param name `function_Param`

https://github.com/googleapis/nodejs-functions/pull/146/files#diff-befd2ad0da13326aa9d2b9089e57ae16a5fa61ac16c2bd566035f10d46ff6e5dR1701

It's being generated as:

  cloudFunctionPath(project: string, location: string, functionParam: string) {
    return this.pathTemplates.cloudFunctionPathTemplate.render({
      project: project,
      location: location,
      function: function_Param, // this one is incorrect
    });
  }

Weird. It should be a camel case. id.get(param.toCamelCase()) template code
And it works for nodejs-speech PR and nodejs-service-center PR. These two both have the reserved words like package and export.

I generated for nodejs-function locally, and it works with functionParam.

Will manual update for nodejs-function with owlbot.

@chingor13 owlbot.py keep the _. Let me remove the hacks in owlbot.py.

Not generator issue.
