Slightly misleading error message (alternative included)

**Describe the bug**

This error implies that wallet adapters must be installed for all wallets supported by the app:

> Your application is presently configured to use the `UnsafeBurnerWalletAdapter`. Find and remove it, then replace it with a
> list of adapters for wallets you would like your application to support. See https://github.com/solana-labs/wallet-
> adapter#usage for an example.

A possible alternative:

> Your application is presently configured to use the `UnsafeBurnerWalletAdapter`. Find and remove it. By default wallet-
> adapter supports all wallet-standard wallets, you may also wish to add specific adapters for wallets you would like your
> application to support. See https://github.com/solana-labs/wallet-adapter#usage for an example.

**To Reproduce**
Start the `packages/starter/example` project.

**Expected behavior**
