samples: update sample to use protos, until typing can be fixed

[juffalow]

Function searchUris takes an object with uri field which is a string and a threatTypes field which is array of numbers, not strings.

If strings are used, it will show error:

Argument of type '{ uri: string; threatTypes: string[]; }' is not assignable to parameter of type 'ISearchUrisRequest'.

Because searchUris first parameters is of type protos.google.cloud.webrisk.v1.ISearchUrisRequest:

interface ISearchUrisRequest {

    /** SearchUrisRequest uri */
    uri?: (string|null);

    /** SearchUrisRequest threatTypes */
    threatTypes?: (google.cloud.webrisk.v1.ThreatType[]|null);
}

And google.cloud.webrisk.v1.ThreatType is:

enum ThreatType {
    THREAT_TYPE_UNSPECIFIED = 0,
    MALWARE = 1,
    SOCIAL_ENGINEERING = 2,
    UNWANTED_SOFTWARE = 3
}

Even in web_risk_service_client.ts it is declared as:

  /**
   * ...
   * @param {number[]} request.threatTypes
   * ...
   */
  searchUris()

This is a bug in our generated types. We want to be able to accept the stringified versions of the enums which are more friendly.

Filed googleapis/gax-nodejs#1205 on our types generator

Thanks @chingor13. In the meantime, I think it makes sense to update the sample. @juffalow, the README is generated from the quickstart. Could you make these changes to samples/quickstart, and the changes will propagate to the README? Thanks.

[juffalow]

Thank @sofisl! I updated the code in samples/quickstart.js and dropped the old commit.

[sofisl]

Sorry, one more request, would you mind adding a TODO comment on the sample like so (above the START tag):
TODO: revert threat types to strings once https://github.com/googleapis/gax-nodejs/issues/1205 is fixed

[juffalow]

Hi @sofisl! I added there the comment. Hope this is the place you mentioned.
