"Install" is not a noun, and while it might be acceptable to use the verb as a noun, it is not correct. Using the correct noun, "installation", increases clarity, especially for non-native English speakers. This change fixes the usage in user-facing text and in developer documentation. Fixes #41620 Built from https://develop.svn.wordpress.org/trunk@41289 git-svn-id: http://core.svn.wordpress.org/trunk@41129 1a063a9b-81f0-0310-95a4-ce76da25c4cd
