Mentorship decline email says the mentor has provided a reason even if they don't

[moshfeu]

When mentors decline a request they allowed to not specify the reason.

The issue

Currently, even if they didn't leave a reason, the email says

They provided the reason below, which we hope will help you find your next mentor:

The solution

Don't include the following part if the reason is empty

find-a-mentor-api/content/email_templates/mentorship-declined.html

Lines 29 to 35 in 4a68ae9

	<p>
	They provided the reason below, which we hope will help you find your next
	mentor:
	</p>
	<pre><%= reason %></pre>
