EPMRPP-117636 || Add a version warning banner for previous documentation versions

[allaprischepa]

Changes

1. Replaced the default DocVersionBanner [link] with a custom one using swizzling to be able to set custom text.
2. Updated styles for warning alerts according to the design
3. Disabled the react/require-default-props rule because defaultProps are deprecated for function components and will be removed in React 19, so there is no point in introducing them just to satisfy this rule

Banner configuration and lint support .eslintrc, docusaurus.config.js	ESLint no longer requires default props. Docusaurus exposes productName through customFields.
Warning alert styles src/css/custom.css	Warning alert variables and themed styles define backgrounds, borders, text, and link behavior.
Version banner component src/theme/DocVersionBanner/index.jsx	The component renders translated labels for unreleased or unmaintained versions and links to the matching document in the latest version. It saves the preferred version when the link is selected.

Warning-banner links may be harder to identify in the dark theme. This is a bounded accessibility concern and does not materially block documentation use.
