Bug: markdown code is converting angle brackets wrong

Summary: When we write left angle bracket (<) within backticks, it shows <. The expected output is to show the angle bracket as is.

Steps to reproduce the behavior:

1. Create a card
2. Add "text" contents and write angle brackets within backticks: `m < n`
3. See the resulting text: m < n.

Expected behavior: The resulting text must be m < n

Screenshots: Attached two screenshots: before and after typing m < n.

Platform:

• I can see this problem from Linux, Windows, and MacOS.
• I am using self-hosted focalboard v0.6.7 on Ubuntu 20.
