Fix Extra Punctuation in "Still Need Help?" Section

[awantika-m]

Issue

Fixes #2016

Description

This PR removes the extra period after the exclamation mark in the "Still Need Help?" section of the DocsHelp component.

Changes Made

• File: components/DocsHelp.tsx
• Changed here to help!. → here to help!

Before

<p data-test='additional-help-description'>
  Learning JSON Schema is often confusing, but don't worry, we are
  here to help!.
</p>

After

<p data-test='additional-help-description'>
  Learning JSON Schema is often confusing, but don't worry, we are
  here to help!
</p>

Why This Change?

Having both an exclamation mark and a period (!.) is a punctuation error. The exclamation mark alone is sufficient to end the sentence.
