[Hotfix] Address URL Formatting Issue Did Not Get Fixed During 0.3.0

[davidgxue]

Description

• A previous PR didn't test thoroughly and had a bug so that it did not address the problem.
• Previous PR: Bugfix: Added changes to update prompt for webapps #306
• Goal is to have different system prompt for different slack vs webapp client
• The previous PR was modifying the user's question prompt not system prompt

Related Issue

closes #301
This issue is supposed to be fixed in 0.3.0, but due to inadequate testing during that PR merge, it wasn't caught that the PR didn't address the problem. The bug is re-discovered after 0.3.0 release.

Tests

1. Sent a request on front end
2. Got URL embedded into the keywords

3. Check Langsmith, metadata has client = webapp 4. Check langsmith, correct system prompt is used
