Bump hardhat from 2.6.0 to 2.9.9 in /examples/hardhat

[dependabot]

Bumps hardhat from 2.6.0 to 2.9.9.

Release notes

Sourced from hardhat's releases.

Hardhat v2.9.9

This release fixes a problem with Hardhat's peer dependencies that was causing some issues for pnpm users.

Hardhat v2.9.8

This release adds support for custom HTTP headers in the forking configuration. This can be useful to, for example, use nodes that have some kind of authorization mechanism:

module.exports = {
  networks: {
    hardhat: {
      forking: {
        url: "...",
        httpHeaders: {
          Authorization: "Bearer token"
        }
      }
    }
  }
};

Thanks @​TimDaub for implementing this!

This version also exposes the formArtifactPathFromFullyQualifiedName method in the Artifacts public interface.

Hardhat v2.9.7

This release fixes a bug (#2742) that was causing block.chainid to be evaluated to 0 inside view functions.

Hardhat v2.9.6

This release fixes an issue that was preventing compilation from working on Windows (#2712, thanks @​tylerK1294!)

Besides that, now the node task is terminated when the server closes (thanks @​zzmp!)

Hardhat v2.9.5

This release fixes a small publish problem in v2.9.4 that shouldn't affect most users.

Besides that, now the eth_getStorageAt method is spec-compliant. This means that the storage slot argument must have a length of 32 bytes (a hex-encoded, 0x-prefixed string of length 66).

Hardhat v2.9.4

This release of Hardhat adds a change that makes it work better with the latest versions of ethers.js. It also includes several bug fixes and some minor features.

• Expand the data object returned by the JSON-RPC response when a transaction or call reverts. Now it also includes the message and data fields. The message is the same message that is part of the response, and it's included to make things work better with ethers.js. The data field includes the return data of the transaction. These fields are included in the responses of the eth_sendTransaction, eth_sendRawTransaction, eth_call and eth_estimateGas methods when they revert.
• Fixed an issue when circular dependencies where present in lazyObject or lazyFunction (issue #1473, thanks @​pcarranzav!)
• Upgrade ethereumjs dependencies (thanks @​LogvinovLeon!)
• Stop publishing tsconfig.json files (issue #2582)
• Fixed an issue when solcjs was being used to compile the project (issues #2554, #2329 and #2004, thanks @​alexdupre!)
• Fixed a problem related to how optional params were printed in the help (thanks @​scnale!)
• Fixed an issue triggered when hardhat_mine was used with solidity-coverage (issue #2467)
• Allow --version flag to be used when not in a Hardhat project directory (thanks @​brianpursley)
• Fixed an OOM error during parallel compilation and added a --concurrency param to the compile task
