Update block-untrusted-fonts-in-enterprise.md

As reported in issue ticket #8687 (Dead link to Dropping the “Untrusted Font Blocking” setting), the outdated link to blogs.technet.microsoft.com just leads to a 404 error and no proper redirect to the existing article.

Thanks to KalleOlaviNiemitalo for noticing, reporting the issue and suggesting the link to the correct page.

Proposed change:
- replace the blogs.technet.microsoft.com URL with a working techcommunity.microsoft.com URL

Whitespace changes:
- add missing MarkDown indent marker compatibility spacing
- normalize bullet point list spacing (from 3 down to 1)
- remove any end-of-line blank space

Closes #8687

To help protect your company from attacks which may originate from untrusted or attacker controlled font files, weve created the Blocking Untrusted Fonts feature. Using this feature, you can turn on a global setting that stops your employees from loading untrusted fonts processed using the Graphics Device Interface (GDI) onto your network. Untrusted fonts are any font installed outside of the `%windir%/Fonts` directory. Blocking untrusted fonts helps prevent both remote (web-based or email-based) and local EOP attacks that can happen during the font file-parsing process.
