As it was discussed in [#13510](https://github.com/bitcoin/bitcoin/pull/13510), it is better to use `#!/usr/bin/env bash` instead of `#!/bin/bash`.

3a0446fad470595db09929695ff02debe12bd4cd script: Add explanatory comment to tc.sh (dscotese)
Pull request description:
This is a replacement for #21289
tc.sh is used to limit bandwidth. I ran it and it is limiting my bandwidth. When I ran it, I got one error. I have not found an explanation anywhere of what the error means, but my best guess is consistent with the result, so I propose the explanatory comment to save others time when they use it and also get the error.

~~Make sure `LC_ALL=C` is set when using `grep` range expressions.~~
Make sure `LC_ALL=C` is set in all shell scripts.
From the `grep(1)` documentation:
> Within a bracket expression, a range expression consists of two characters separated by a hyphen. It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set. For example, in the default C locale, `[a-d]` is equivalent to `[abcd]`. Many locales sort characters in dictionary order, and in these locales `[a-d]` is typically not equivalent to `[abcd]`; it might be equivalent to `[aBbCcDd]`, for example. To obtain the traditional interpretation of bracket expressions, you can use the C locale by setting the `LC_ALL` environment variable to the value C.

This commit adds a Linux script that uses tc and iptables to
limit outgoing bandwidth to Bitcoin nodes. All tcp connections with
a source or destination port of 8333 are limited to the chosen rate.
It does not alter the incoming bandwidth. Additionally, outgoing
bandwidth to a host on a local LAN (defined by the LOCALNET variable)
is not limited.
