Add Organization PAT fields to InstallationPermissions struct

[hi120ki]

In the article "Organization APIs for fine-grained PATs management", following new 2 permissions are added to GitHub Apps

• organization_personal_access_tokens
• organization_personal_access_token_requests

These permissions are used for getting and updating GitHub Organization's Fine-grained PAT's lists, requests, revokes.

APIs of Organization permissions for "Personal access tokens"
APIs of Organization permissions for "Personal access token requests"

We can test these permissions following test codes, and successfully I got installation token from GitHub.

package main

import (
	"context"
	"log"
	"net/http"

	"github.com/bradleyfalzon/ghinstallation/v2"
	"github.com/google/go-github/v64/github"
)

func main() {
	ctx := context.Background()
	tr := http.DefaultTransport
	itr, err := ghinstallation.NewAppsTransportKeyFromFile(tr, <your-app-id>, <your-private-key-path>)
	if err != nil {
		log.Fatal(err)
	}
	client := github.NewClient(&http.Client{Transport: itr})
	token, _, err := client.Apps.CreateInstallationToken(
		ctx,
		<your-installation-id>,
		&github.InstallationTokenOptions{
			Permissions: &github.InstallationPermissions{
				OrganizationPersonalAccessTokens:        github.String("read"),
				OrganizationPersonalAccessTokenRequests: github.String("read"),
			},
		})
	if err != nil {
		log.Fatal(err)
	}
	log.Println(token.GetToken())
}
