[BUG] Strikethrough markup not being highlighted/rendered with strikethrough

[halleysfifthinc]

Describe the bug

1. Strikethrough'ed text in e.g. markdown is not being highlighted with the strikethrough
   

The issue is due to a typo (or an upstream change in the highlight name?) at lua/gruvbox.lua#L1017

    ["@markup.strike"] = { strikethrough = config.strikethrough },

where @markup.strike should be @markup.strikethrough. I can confirm that adding

      ["@markup.strikethrough"] = { strikethrough = true }

to overrides produces the desired behavior.

Expected behaviour

It should look like:
