🪲 [Fix]: Fix linter settings and docs (#50)

## Description

This pull request makes minor adjustments to the Markdown linter
configuration. The main change is the disabling of the duplicate heading
check to allow repeated headings like "INPUTS" and "OUTPUTS", and a
small formatting update to the punctuation rule.

- Markdown linting configuration updates:
* Disabled the `MD024` rule to permit duplicate headings, such as
"INPUTS" and "OUTPUTS" (`.github/linters/.markdown-lint.yml`).
* Changed the punctuation list for `MD026` to use single quotes for
consistency (`.github/linters/.markdown-lint.yml`).
