Fix typos and grammar errors

[mintlify]

Fixed 8 typos and grammar errors across 3 documentation files: deploy/authentication-setup.mdx (redploys → redeploys, Your host → You host), deploy/ghes.mdx (2.Click → 2. Click, reccomend → recommend), and deploy/route53-cloudfront.mdx (Your websites → Your website's). All changes validated.
