This patch introduces a namespace declaration for the
Wikimedia\Http to MultiHttpClient and establishes a class
alias marked as deprecated since version 1.43.
Bug: T353458
Change-Id: I4ebc1a3b496de08b2b430301da376578d13fcfe6
This was done automatically using the
`Universal.WhiteSpace.CommaSpacing` sniff, which will be included in the
next release of the MW PHPCS config.
Some of these have been adjusted manually where the autofix broke
vertical alignment.
