Add ids to buttons to make e2e testing easier

[Shelob9]

I'm struggling to click "Grant Example Support Access" and "Revoke Access" buttons. Would be way easier if they had ids I could target.

@zackkatz Those buttons are created here, right?

client/src/Admin.php

Lines 396 to 419 in 7c4a9a2

	<div class="tl-{{ns}}-auth tl-{{ns}}-{{has_access_class}}">
	{{header}}
	<section class="tl-{{ns}}-auth__body">
	<h2 class="tl-{{ns}}-auth__intro">{{intro}}</h2>
	<div class="tl-{{ns}}-auth__content">
	<header class="tl-{{ns}}-auth__header">
	{{auth_header}}
	</header>
	<div class="tl-{{ns}}-auth__details">
	{{details}}
	</div>
	<div class="tl-{{ns}}-auth__response" aria-live="assertive"></div>
	{{notices}}
	<div class="tl-{{ns}}-auth__actions">
	{{button}}
	</div>
	</div>
	<div class="tl-{{ns}}-auth__secured_by">{{secured_by_trustedlogin}}</div>
	</section>
	<footer class="tl-{{ns}}-auth__footer">
	{{footer}}
	{{reference}}
	</footer>
	</div>';

• Revoke access button:

  client/src/Admin.php

  Line 363 in 7c4a9a2

  'revoke_access_button' => sprintf( '<a href="%s" class="button button-danger alignright">%s</a>', $revoke_url, esc_html__( 'Revoke Access', 'trustedlogin' ) ),

• Generate access button

  client/src/Admin.php

  Line 389 in 7c4a9a2

  'button' => $this->generate_button( 'size=hero&class=authlink button-primary', false ),

I asked Shawn if he had a better solution, he agreed with this solution
