Help Wanted: Code blocks within tabbed content blocks are being double spaced

[devinbinnie]

Steps to reproduce:
Create a code block within some tabbed content. Example:

mattermost-developer-documentation/site/content/contribute/more-info/desktop/developer-setup/ubuntu.md

Line 2 in 6ae6784

2. Install NodeJS from [NodeSource](https://github.com/nodesource/distributions#installation-instructions):

Expected: The code block should render without extra spacing

Observed: The code block adds arbitrary spaces between lines

Potential cause: It's likely an issue with the Hugo template generator. I noticed that the generated HTML is adding a newline after each line within the span tag, so it's getting double spaced.

Can I get assigned to this please? Seems that no one wants to work on it
