Grammar file produces a hyperlink even when no value is given to it in the Language files

[Naveenaidu]

Grammer file produces a hyperlink to the respective grammar files when we provide the entry to it in the language file.

Example:- C.yaml
grammar_file: https://github.com/antlr/grammars-v4/blob/master/c/C.g4

After the site is deployed, the results are rendered as: https://coast.netlify.com/c/
As you see here a hyperlink is produced for the grammar file.

But

When the grammar file field is empty or not mentioned in the language file such as Bash.yaml or Swift.yaml where the grammar file is not present.

When these files get rendered, they display the text None which hyperlinks to a page which do not exist.

Grammar File	None

This needs to be fixed. Instead of showing None with a hyperlink. It should only show None without any hyperlinks.
