[BUG] ini.options_present can squash duplicate keys without notifying

Description
The ini.options_present state seems to be incapable of detecting duplicate options within a section. I haven't looked at the code yet, but I suspect it's reading the file in as a data structure, and duplicate keys are "squashed" during that process such that the last option in the section "wins".

Steps to Reproduce the behavior
The following code can be used to reproduce the problem:

file_manage_/tmp/test.ini:
  file.managed:
    - name: /tmp/test.ini
    - contents: |
        [main]
        hello=goodbye
        hello=world

ini_manage_/tmp/test.ini:
  ini.options_present:
    - name: /tmp/test.ini
    - strict: true
    - sections:
        main:
          hello: world

cat_/tmp/test.ini:
  cmd.run:
    - name: cat /tmp/test.ini

Note that the ini.options_present state does not report changes, but the file has been changed.

Swapping the first and second occurrence of the option will then show the change.

Additional context
Related (at least in part) to the logic and outcome experienced in #65191

Start at the Salt ini.options_present state entry point and reproduce the issue with the YAML configuration shown, comparing both duplicate-key orderings. Trace how the INI file is read and how changes are detected; done means modifications caused by duplicate options are reported consistently, with regression coverage for the reproduced behavior.
