Portal Experience update removing UI HTML

[Springstone]

This pull request updates several tooltip texts in the eslz-portal.json file to improve clarity and consistency. The main changes involve reformatting tooltips to remove embedded HTML links and instead provide plain URLs with descriptive text in parentheses. Additionally, minor corrections were made to some labels and text for improved readability.

The most important changes are:

Tooltip and Documentation Link Formatting:

• Updated all tooltips to use plain URLs with descriptive text in parentheses, replacing HTML anchor tags and <br> tags for better readability and consistency across the portal. This affects tooltips for classic resources, VM disks, subnet privacy, Key Vault guardrails, backup and recovery, guest attestation, diagnostic settings, and multiple Microsoft Defender for Cloud features.

Label and Text Improvements:

• Removed the "New" HTML tag from the "Enforce subnets should be private" label for a cleaner appearance.
• Fixed a typo in the "Security subscription (recommended)" tooltip, changing "dont" to "do not" for proper grammar.

General Documentation Improvements:

• Reformatted informational text in the Log Analytics InfoBox to use numbered plain URLs with descriptions instead of HTML lists and links.

These changes enhance the user experience by making tooltips and documentation links clearer and more accessible, and by improving overall text consistency throughout the portal.
