Subject: [PATCH] build: fix windows installer build for NSIS v3.05 (#22821)

With the update to a newer AppVeyor build image, creating the Windows
installer no longer worked because of a string quoting error in EnvVarUpdate.nsh.

This applies the fix recommended in https://stackoverflow.com/questions/62081765.
