Allow custom text while forwarding messages

Title

Allow custom text while forwarding messages.

Description

Rocket.Chat already supports message forwarding, but users need the ability to add text when forwarding. Similar to quoting, this would allow adding context or commentary, improving clarity in communication.

Steps to Reproduce

1. Forward a message.
2. Notice there's no option to add extra text.

Expected Behavior

• The UI should include an editable text area when forwarding a message.
• Users should be able to add any additional commentary that appears together with the forwarded message.
• The additional text should seamlessly integrate with the forwarded content, similar to quoting a message.

Actual Behavior

• Only the original message is forwarded.
• There is no built-in method for users to add their own text to the forwarded message.
• Users must rely on workarounds (like sending a separate message) to provide context.

Additional Context

• This enhancement would streamline the workflow by allowing more expressive and informative message sharing.
• It directly addresses user needs for clearer communication in various contexts.
