Incompatibility between `@flashbots/ethers-provider-bundle` (v1.x.x) and ethers (v6.x.x)

I found an incompatibility issue when using `@flashbots/ethers-provider-bundle` version 1.x.x with ethers version 6.x.x, resulting in a module not found error.

**Component:** `@flashbots/ethers-provider-bundle`

**Steps to reproduce bug:**

1. Set up a Node.js project with `ethers` v6.x.x and `@flashbots/ethers-provider-bundle` v1.x.x installed as dependencies in `package.json`.
2. Write or use existing TypeScript/JavaScript code that imports and attempts to initialize `FlashbotsBundleProvider` from `@flashbots/ethers-provider-bundle`.
3. Run the code or tests that involve this import and initialization.

**Expected behavior:**

The `FlashbotsBundleProvider` should be imported and initialized successfully without errors when used with a compatible version of ethers v6, as indicated by the Flashbots library documentation for v1.x.x.

**Actual behavior:**

When running the code, the following error occurs:
```bash
Cannot find module '@ethersproject/web' from 'node_modules/@flashbots/ethers-provider-bundle/build/index.js'
```

This error indicates that the Flashbots library is attempting to import a module (`@ethersproject/web`) that is part of the ethers v5 structure but is not present or has been moved/removed in ethers v6.

**Version number:**

* `ethers`: ^6.11.1
* `@flashbots/ethers-provider-bundle`: ^1.0.0 (the latest version)
* Node.js: v20.18.1

**Operating system:**

Windows 11
