Update-MarkdownHelp adding back in a space that VSCode removes

[rkeithhill]

Steps to reproduce

Set up VSCode to trim trailing whitespace.
Create a markdown for a function.
Save it from VSCode with trim trailing whitespace enabled.
Run Update-MarkdownHelp on the markdown file.

Expected behavior

The command should not modify the file because we haven't changed it.

Actual behavior

The command is adding back in a space after Aliases::

Environment data

v0.7.2

Sure would be nice if platyPS didn't add the space after Aliases: in the first place. That would play better with editors like VSCode where users can configure the editor to trim trailing whitespace automatically which is very useful for PowerShell scripts.

Agree, it would be nice to have.
Should be pretty easy to add.

Might look at taking this one on, still in the latest build, and it is annoying me :)

[vors]

Ah that's a good one! @BernieWhite let me know if you have any questions

[BernieWhite]

Thanks. So do you think any sort of feature switches are going be required, or will trailing spaces always be removed?

[BernieWhite]

@vors This one turned out to be broader then expected. Existing help used in unit tests use trailing whitespace in multiple places.

It wasn't something that could easily be solved, so the fix was scoped to only address yaml blocks used for header and parameters, which will address @rkeithhill original request.

Always removed

Fixed in #225
