[stable27] fix: Fix resolved nextcloud/files dep version and user quota parsing

[Pytal]

• Fix [Bug]: v27.1.6 - Deleted files view (files_trashbin) does not show deleted files #43134
• Fix Cannot set user quota with uneven values using locales that use a comma as decimal separator #18468

Summary

• Followup [stable27] Roll back erroneous nextcloud/files update #43259

Because of the package resolution algorithm nextcloud/files is resolved to v3.0.0

├─┬ @nextcloud/dialogs@4.2.4
│ └── @nextcloud/files@3.0.0 deduped
└── @nextcloud/files@3.0.0

So the previously used parseWebdavPermissions() function is no longer available

With this fix the correct non-breaking version is resolved

├─┬ @nextcloud/dialogs@4.2.4
│ └── @nextcloud/files@3.1.0
└── @nextcloud/files@3.0.0-beta.8

To fix the potentially breaking resolution of nextcloud/files v3.1.0 for nextcloud/dialogs we need to pin it in dialogs as well nextcloud-libraries/nextcloud-dialogs#1226 and bump it

New dependency tree:

├─┬ @nextcloud/dialogs@4.2.5
│ └── @nextcloud/files@3.0.0-beta.21
└── @nextcloud/files@3.0.0-beta.8
