Docs: Rename example script

[GaryJones]

The script will install (register) one or more Standards to PHP CodeSniffer, not the individual Sniffs.

Proposed Changes

Rename the script example in the Docs to clarify intent.

Optionally, it calls also be called register-codestandards, since the installation of the files has already been done by Composer, and this script would just re-register the Standard with PHP CodeSniffer. I've left it as install-codestandards for now though, as it may be perceived to be easier to remember, even if not technically accurate.

Looks good to me. If @frenck agrees this can be merged/tagged/released.

It might be smart to change the jargon in the wiki as well:

To gain more widespread support for PHPCodeSniffer installers (not just this project) it is important that maintainers of custom codesniffs adapt using the "type" : "phpcodesniffer-standard" in their project's composer.json. ¹

Adding the following line to the composer.json will make it possible for such packages to install this custom sniff using composer ²

I've also updated the wiki entries mentioned above.
