use GitHub Flavored Markdown

[SethTisue]

over at https://github.com/scala/scala.github.com/blob/master/_config.yml we have:

markdown: kramdown
kramdown:
  input: GFM

it would be great to standardize on the same thing here. for multiple reasons:

1. GitHub Flavored Markdown is IMO what our contributors are likeliest to expect
2. it's confusing and error-prone for contributors anytime the two sites have technical differences (and makes it harder to move content between the two sites)

👍 Agree!

Hey, do you still need help here? if yes can you please brief me what needs to be done here? thanks

@muskan3006 Looking at _config.yml -

scala-lang/_config.yml

Lines 7 to 8 in 2c1afd5

	markdown: kramdown
	highlighter:

it doesn't say

markdown: kramdown
kramdown:
  input: GFM

so I think we still need help on this task.

Here's what is likely needed.

step 1

Follow readme (https://github.com/scala/scala-lang) to setup a local environment to build scala-lang.org using the exact version of Jekyll etc.

step 2

Change _config.yml and add:

kramdown:
  input: GFM

step 3

Manually go through the pages to see if the rendering looks different from https://scala-lang.org/, and fix them appropriately. If there's no one-to-one feature available for some reason, let us know here.

@muskan3006 that'd be awesome! I agree with Eugene's assessment.
