Bump hardhat from 2.9.3 to 2.12.7 in /local-setup-testing

[dependabot[bot]]

Bumps hardhat from 2.9.3 to 2.12.7.

Release notes

Sourced from hardhat's releases.

hardhat@2.12.7

Changes

• e443b3667: Added an option in Hardhat Network to allow mining blocks with the same timestamp

• c23a1cac4: Added support for the http_proxy environment variable. When this variable is set, Hardhat will send its requests through the given proxy for things like JSON-RPC requests, mainnet forking and downloading compilers.

  We also removed support for the HTTP_PROXY and HTTPS_PROXY environment variables, since http_proxy is the most commonly used environment variable for this kind of thing. Those variables could only be used for downloading compilers.

  Finally, we also added support for no_proxy, which accepts a comma separated list of hosts or "*". Any host included in this list will not be proxied.

  Note that requests to "localhost" or "127.0.0.1" are never proxied.

• 69546655e: Added support for sending batch requests through WebSocket to the Hardhat node (thanks @​tenbits!)

• 6bf1673bb: Added a config validation for the number of optimizer runs used (thanks @​konarshankar07!)

Hardhat v2.12.6

Features

• Added support for pnpm during project creation (thanks @​Hopsken!)
• Added a version field to the Hardhat Runtime Environment (thanks @​konarshankar07!)

Bug fixes

• Fixed a problem with impersonated-sender transactions sometimes resulting in duplicate transaction hashes (issue #1963)

Other changes

• Added a minor clarification to the help output of the flatten task
• Upgraded the versions of mocha and @types/mocha used by Hardhat
• Upgraded the version of undici used by Hardhat.
• Removed the message linking to the 2022 Solidity Survey
• Added a new subtask to the compile task that will be used by the hardhat-foundry plugin.

Hardhat v2.12.5

• The full return data of unrecognized custom errors is now shown in error messages
• Fixed a bug that was causing the flatten task to produce non-deterministic results
• Fixed a bug when gasPrice was set to "auto", which is the default configuration when connecting to a JSON-RPC network. This bug was preventing the results from eth_feeHistory from being used when they should.
• Added an experimental environment variable flag to disable the local installation check (thanks @​arijoon!)

Hardhat v2.12.4

This release fixes a small issue that was affecting our VSCode extension in some edge cases.

It also includes a non-intrusive message promoting this year's Solidity Developer Survey.

Hardhat v2.12.3

• Added a new hardhat_metadata RPC method
• Trim leading and trailing spaces in mnemonics (thanks @​winor30!)
• Pending blocks now include the bloom field (thanks @​InoMurko!)
• A better error is shown if a Solidity file makes an import through its own package name (thanks @​KaanKC!)
• Added a getBuildInfoSync function to the hre.artifacts object (thanks @​emretepedev!)
