For the minimatch issue, the dependabot warning comes from the fact that the solidity-coverage dependency in @nomicsfoundation/hardhat-toolbox uses mocha v7.1.2 which uses an old version of minimatch.

I have reported in an already open PR that upgrade mocha in the Solidity coverage repo: sc-forks/solidity-coverage#758 (comment)
