--properties-array-brackets does not seem to work when reading properties files

[Northcode]

Describe the bug
--properties-array-brackets does not seem to work when reading properties files.

Version of yq: v4.44.6
Operating system: linux
Installed via: archlinux package https://archlinux.org/packages/extra/x86_64/go-yq/

Input Properties

arr[0].name=test
arr[0].value=5
arr[1].name=test2
arr[1].value=10

Command
The command you ran:

yq -p=props -o=y --properties-array-brackets input.properties

Actual behavior

arr[0]:
  name: test
  value: "5"
arr[1]:
  name: test2
  value: "10"

Expected behavior

arr:
  - name: test
    value: "5"
  - name: test2
    value: "10"

This might be intended behavior, and the option is only supported for properties output instead of input.
But it wasn't very clear from the documentation since that also mentions .0 style arrays and those do work for both input and output.

$ cat | yq -p=props -o=y -
arr.0.name=test
arr.1.name=test2
^D
arr:
  - name: test
  - name: test2

$ cat | yq -p=props -o=y --properties-array-brackets -
arr[0].name=test
arr[1].name=test2
^D
arr[0]:
  name: test
arr[1]:
  name: test2

If it is not intended to work for inputs and only output, then consider this a feature request.
