[go1.24 support] bump golangcilint

[hannahkm]

What does this PR do?

Bumps the version of golangci-lint being used to be the latest version.

Motivation

The earliest version of golangci-lint to support Go v1.24 is v1.64, whereas we were previously at v1.63. To prevent failures on the main branch, we should upgrade the linter.
