CSS property ::v-deep not migrated correctly

[cnotv]

Description

The ::v-deep property has not been correctly migrated, as it's supposed to be replaced by the function :deep() which has to include the selector as argument.

Several styling seems to be affected which will require to be corrected en-masse.

Example occurrences:

• Vue3: Yaml editor and other codemirror components' theme rendering is off #11701

Notes

All these occurrences are bad practices and have to be corrected with more time afterward: #11943

23 files require manual correction due to the complexity and variety of syntax.
