Don't trim license template lines

[iamdanfox]

Before this PR

PRs were being made to helpfully chop the whitespace off the front of lines:

- *     http://www.apache.org/licenses/LICENSE-2.0
+ * http://www.apache.org/licenses/LICENSE-2.0

We don't want this as the authoritative license has the whitespace prefix:

gradle-baseline/gradle-baseline-java-config/resources/copyright/001_apache-2.0.txt

Line 7 in e1f9438

http://www.apache.org/licenses/LICENSE-2.0

After this PR

==COMMIT_MSG==
Copyright header enforcement now includes any leading and trailing whitespace on lines
==COMMIT_MSG==

Possible downsides?

• trailing whitespace is generally considered a bad thing. If a template has trailing whitespace, it'll be propagated everywhere. solution is to just not have trailing whitespace in your templates I think.
