[PATCH v3 02/11] contrib: remove "examples" directory

[Patrick Steinhardt <ps@pks.im>]

The "examples" directory used to contain scripted versions of some of
our builtins. These have all been removed in 49eb8d39c78 (Remove
contrib/examples/*, 2018-03-25), but we left a note in the directory to
make it discoverable that there used to be examples.

It is unlikely that anybody still looks at these examples more than 7
years after they have been removed. Remove the note and its directory.

-This directory used to contain scripted implementations of builtins
-that have since been rewritten in C.
-
-They have now been removed, but can be retrieved from an older commit
-that removed them from this directory.
-
-They're interesting for their reference value to any aspiring plumbing
-users who want to learn how pieces can be fit together, but in many
-cases have drifted enough from the actual implementations Git uses to
-be instructive.
-
-Other things that can be useful:
-
- * Some commands such as git-gc wrap other commands, and what they're
-   doing behind the scenes can be seen by running them under
-   GIT_TRACE=1
-
- * Doing `git log` on paths matching '*--helper.c' will show
-   incremental effort in the direction of moving existing shell
-   scripts to C.
