Drop unsupported properties from Single Checkbox

[brotkrueml]

"autoSizeMax", "multiple" and "size" don't make sense for this render type and aren't supported for single checkboxes.

See also: https://github.com/TYPO3/typo3/blob/main/typo3/sysext/backend/Classes/Form/Element/SelectCheckBoxElement.php

Releases: main, 13.4, 12.4

In that case the anchors must be moved, not removed, preferably to a message why the content was removed

[brotkrueml]

Which anchors?

The Select Checkbox does not have these three properties, therefore they should not be mentioned.

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-12.4 12.4
# Navigate to the new working tree
cd .worktrees/backport-12.4
# Create a new branch
git switch --create backport-1362-to-12.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 9481c1d4b1935e2e9970c49f90fbbfc5f1d518b3,aca809c06c529beb2882e9afaa4013adb5503b7c
# Push it to GitHub
git push --set-upstream origin backport-1362-to-12.4
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-12.4

Then, create a pull request where the base branch is 12.4 and the compare/head branch is backport-1362-to-12.4.

Automatic backport to 12.4 is not possible, please make a separate PR for 12.4 if desirec
