Automatic merge from submit-queue (batch tested with PRs 50257, 50247, 50665, 50554, 51077)

Remove incorrect patch-merge directives.

**What this PR does / why we need it**:

Directives were misplaced for the following types:

- MatchExpressions
- Taints
- Tolerations

Per the discussion in #46547, we cannot fix these because it would cause backwards-compatibility problems. Instead, remove the incorrect ones so they don't mislead users. This has no impact on behavior.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
