chore: bump tailwindcss to the latest version

[mman]

tailwindcss provides set of predefined CSS classes for colouring and layout as well as custom layout breakpoints, and colors. postcss scans all produced html content, and together with autoprefixer replaces all used CSS classes in the app with the tailwindcss provided ones.

Naive upgrade of tailwindcss broke the layout and colors, so it will require step by step approach coordinated with updating postcss.

This one breaks our dark theme and styling. Needs investigation.

-    "tailwindcss": "^3.2.7",
+    "tailwindcss": "^3.3.0",

Here is the blog post announcing the update: https://tailwindcss.com/blog/tailwindcss-v3-3

And here is the appropriate GitHub release: https://github.com/tailwindlabs/tailwindcss/releases/tag/v3.3.0

postcss* and css-loader seem to be safe.
