add `.php-ini` and `.php-version` to expected files

[JohnRDOrazio]

Even though the two files .php-ini and .php-version are not directly provided by nextcloud, they are however provided by my Plesk setup. It get's a bit annoying to have to move them out of the nextcloud folder in order to do the update, and then move them back in again after. I can't see any counter-indication to including them in the "expected" list?

updater/index.php

Lines 247 to 297 in 3b634b9

	private function getExpectedElementsList(): array {
	$expected = [
	// Generic
	'.',
	'..',
	// Folders
	'.reuse',
	'.well-known',
	'3rdparty',
	'apps',
	'config',
	'core',
	'data',
	'dist',
	'l10n',

	'AUTHORS',
	'CHANGELOG.md',
	'COPYING',
	'COPYING-AGPL',
	'occ',
	'db_structure.xml',
	];
	return array_merge($expected, $this->getAppDirectories());
	}

May I create a PR that addresses this?

[JohnRDOrazio]

I tested adding the two mentioned files to the expected files, and the builtin update went smoothly. Perhaps the related PR could be considered?

Given these are atypical filenames, maybe #372 makes more sense. Though I'm hesitant to make it so easy to ignore non-distributed files being in the installation folder, since it can lead to weird problems.
