Document how to install it, the package name

[idc77]

Describe the bug

This might sound like a beancounter issue, but I came from some issue where the solution had twMerge so I went and searched and found this repository.
But, maybe I'm blind, I don't see the package name anywhere.

So my suggestion is to add lines like

npm i tailwind-merge
pnpm add tailwind-merge
yarn add tailwind-merge
bun install tailwind-merge

Sometimes the packages are named differently than the repo name.

To Reproduce

Expected behavior

Environment

• tailwind-merge version: [e.g. 1.13.1]

Additional context

Makes sense, I'll add them to the configuration docs.
