git-gui: Visualize * History does nothing on macOS

[Ilya Kulakov <kulakov.ilya@xxxxxxxxx>]

Both "Visualize <branch>'s History" and "Visualize All Branch History" do nothing on macOS. In the terminal it logs:

Error in startup script: 58:103: execution error: Not authorized to send Apple events to System Events. (-1743)
    while executing
"exec osascript -e [format {
        tell application "System Events"
            set frontmost of processes whose unix id is %d to true
        end te..."
    invoked from within
"if {[tk windowingsystem] eq "aqua"} {
    exec osascript -e [format {
        tell application "System Events"
            set frontmost of processes ..."
    (file "/opt/homebrew/bin/gitk" line 12321)

The relevant code at https://github.com/git/git/blob/0f3415f1f8478b05e64db11eb8aaa2915e48fef6/git-gui/git-gui.sh#L271-L279 should not be fatal, because the permission to access "System Events" and arbitrarily manipulate windows is optional.
