Following this figma, this PR adds EOL tag for Consul Dedicated and updates warning message.

Consul is going EOL on 12th Nov, we would need this to deployed on the same day.

Requested review scope:

• Content touched by the PR only (typos, clarifications, tips)
• Code test (command and code block changes)

Review urgency:

• ASAP (bug fixes, broken content, imminent releases)
