Added vale substitution warning for variations of "log into" -> "log in to"

[wildmanonline]

This PR adds the following Vale substitution warnings:

• "[Ll]ogin to": log in to
• "[Ll]og into": log in to
• "[Ll]ogged into": logged in to
• "[Ll]ogging into": logging in to

Incorrect instances of these terms were fixed in the /docs/products/ section.
