Bug: `AddSocialAccounts` and `DeleteSocialAccounts` of UsersService return Invalid input

[Not-Dhananjay-Mishra]

According to API docs of AddSocialAccounts it accepts account_urls as body parameter. However, in the current implementation, accountURLs is passed directly.
It should instead be passed as:

req, err := s.client.NewRequest("POST", u, socialAccountRequest{AccountURLs: accountURLs})

or we can make a Struct for it (with struct it will be BREAKING CHANGE)

With this change, accountURLs will be sent in the correct format:
{"account_urls":["https://facebook.com/GitHub","https://www.youtube.com/@GitHub"]}

go-github/github/users_social_accounts.go

Lines 50 to 64 in 9e7e51b

	func (s *UsersService) AddSocialAccounts(ctx context.Context, accountURLs []string) ([]*SocialAccount, *Response, error) {
	u := "user/social_accounts"
	req, err := s.client.NewRequest("POST", u, accountURLs)
	if err != nil {
	return nil, nil, err
	}
	var accounts []*SocialAccount
	resp, err := s.client.Do(ctx, req, &accounts)
	if err != nil {
	return nil, resp, err
	}
	return accounts, resp, nil
	}

same with DeleteSocialAccounts API docs

go-github/github/users_social_accounts.go

Lines 71 to 79 in 9e7e51b

	func (s *UsersService) DeleteSocialAccounts(ctx context.Context, accountURLs []string) (*Response, error) {
	u := "user/social_accounts"
	req, err := s.client.NewRequest("DELETE", u, accountURLs)
	if err != nil {
	return nil, err
	}
	return s.client.Do(ctx, req, nil)
	}

To reproduce the issue:

client := github.NewClient(tc)
acc, res, err := client.Users.AddSocialAccounts(ctx, []string{"https://www.example.com"})
if err != nil {
	fmt.Printf("Error adding social accounts: %v\n", err)
	return
}
fmt.Printf("Added Social Accounts: %+v\n", acc)
fmt.Printf("Response: %+v\n", res)

This results in the following error:

Error adding social accounts: POST https://api.github.com/user/social_accounts: 422 Invalid request.

Invalid input: `["https://www.example.com"]` is not of type `object`. []

I can provide a PR to fix it.
