[UI]: Migrate react-tooltip usages to CustomTooltip from @sistent/sistent

[Maanvi212006]

Description

This PR fixes #7751

Replaced all usages of react-tooltip with CustomTooltip from @sistent/sistent across the codebase, consistent with the project's design system and existing usage in src/components/CopyValue/index.js.

Files changed:

• src/components/blog-view-tooltip.js
• src/components/Landscape-Table/index.js
• src/components/SMI-Table/index.js
• src/sections/Landscape/categories.js
• src/sections/Learn-Layer5/Chapters/index.js

Notes for Reviewers
All 5 files pass syntax check and no react-tooltip imports remain in the codebase

Hi @rishiraj38, thanks for the review!

I looked into the build errors and they appear to be pre-existing issues unrelated to this PR's changes. The failing errors are:

• Can't resolve './LandscapeTable.style'
• Can't resolve '../../assets/images/landscape/passing.svg'
• Can't resolve '../../assets/images/landscape/failing.svg'

These imports were already present in src/components/Landscape-Table/index.js before my changes. This PR only replaces react-tooltip imports with CustomTooltip from @sistent/sistent — no paths or imports were added or modified beyond that.

Could you confirm whether these errors exist on the master branch as well? Happy to investigate further if needed!
