renewed fix: update error message of /p remove <player> if player does not need to be removed

[TheJonstone]

Overview

This pull request update an error message that was already included in pull request #3734 in PlotSquared v6.
Unfortunately, the change from back then was not adopted in v7, hence the request to reintegrate this change now.

Notice PR #3734 : The placeholder “member.player_not_removed” already exists.
In v7, only the reference to this placeholder is missing in the Remove.java command.

Description

Update/Changes the message if you try to remove a player from a plot, which is not added, trusted or denied from the plot to make it more clear, why the command failed.

How can it be that the old PR change is not included? The branch v6 was renamed to main.

The earlier merged change of Xaver was removed by mistakes with the merge-conflict resolving of commit 6efd581. GitHub doesn't show all changes of 6efd581, because the commit is too large. Here is the full patch from the IDE.

                 player.sendMessage(
-                        TranslatableCaption.of("member.player_not_removed"),
-                        Template.of("player", args[0])
+                        TranslatableCaption.of("errors.invalid_player"),
+                        TagResolver.resolver("value", Tag.inserting(Component.text(args[0])))
                 );

I have looked at all of 6efd581 modified classes. It could affect a more code changes. Perhaps more small PRs will follow.
