Appendix C: core.editor command for TextEdit incorrectly uses --add

[Sophismata]

Which version of the book is affected?

The online book: https://git-scm.com/book/en/v2/Appendix-C:-Git-Commands-Setup-and-Config

Describe the bug:

The command to set your core.editor setting for Text Edit is listed as
git config --global --add core.editor "open -W -n"
it should be
git config --global core.editor "open -W -n" (no --add parameter)

Steps to reproduce:

View Appendix C and look at the line for TextEdit (macOS)

Expected behavior:

The command should be git config --global core.editor "open -W -n", which is in line with all the other core.editor commands and won't accidentally add (potentially) two entries for the setting.

Desktop:

• Operating system: Windows 10 Pro
• Browser/application: Chrome
• Browser/application version: 85.0.4183.121 (64 Bit)
