Is your feature request related to a problem?

Some information on about page is outdated, and some of the links on the page are broken, but the info can only be updated using the Custom Locale Plugin

Describe the solution you'd like

• Fixing a typo / misspelling on the word "connecting" (should be connected)
• Updating the link to this article
• Adding the iD icon in the second-to-last sentence.

Shoud be done for OJS 3.2.1 as well

Describe alternatives you've considered

• Disabling the about page in the plugin
