fix: change project id type

[ynhummel]

What does this PR do?

We were having problems with ServerProject.ID, when deploying a server, our API expects it to be a string, but when we Read the server information, our API(v2) returns a number. In order to solve this, this PR changes project ServerProjectID to interface{}, Internally golang is able to coerce this in the needed type (int64 for get, string for post)

Description of Task to be completed?

• Change ServerProject.ID type to interface{}

How should this be manually tested?

By using golang test suit to run the tests related to Servers:

LATITUDE_AUTH_TOKEN=<API-TOKEN> LATITUDE_TEST_ACTUAL_API=true go test -timeout 30s -run "^TestAccServerBasic$"

Or for manual testing use go get to download this branch:

go get github.com/latitudesh/latitudesh-go@fix/get-servers

Usage:

func main() {
    client := latitude.NewClientWithAuth("Latitude.sh", "<API-TOKEN>", nil)

    createAttr := latitudesh.ServerCreateAttributes{
        Project:         "qa",
        Plan:            "c3-small-x86",
        Site:            "SAO2",
        OperatingSystem: "ubuntu_22_04_x64_lts",
        Hostname:        "server-hostname",
    }

    createData := latitudesh.ServerCreateData{
        Type:       "server",
        Attributes: createAttr,
    }

    createReq := latitudesh.ServerCreateRequest{
        Data: createData,
    }

    ser, res, err := client.Servers.Create(&createReq)
    if err != nil {
        fmt.Println(err)
    }

    fmt.Printf("Status: %s\n", res.Status)
    fmt.Println(ser)
}
