Subject: [PATCH] [BUGFIX] Remove leading slash from backendLogo path
As the extension configuration field `backendLogo` isn't resolved
by `TYPO3\CMS\Backend\Controller\LoginController::getUriForFileName()`,
it is in contrast to other fields (e.g. loginLogo or loginBackgroundImage)
not possible to add a path with a leading slash.
As this is neither explicit allowed nor disallowed, this unifies the
behavior by removing a possible leading slash from the defined path
before it gets resolved as it's already the case for the other fields.
Resolves: #89636
Releases: master, 9.5
