Walkthrough

This pull request addresses compatibility issues for projects that do not support Less by refactoring the tooltip styling from Less to CSS. It resolves issues #3088 and #3148 by ensuring that the tooltip styles are correctly applied without relying on Less-specific features.

Changes

Files	Summary
package.json	Updated dependencies to reflect changes in styling approach.
index.less (shared/styles/tooltip)	Modified import statements to align with new styling approach.
index.css (ui/tooltip)	Introduced new CSS file for tooltip styling, replacing Less.
index.less (ui/tooltip)	Removed old Less file and its contents.
index.ts (ui/tooltip)	Updated import statement to use CSS instead of Less.
