fix: pin golangci-lint version to v1

From golangci-lint's changelog:
"[v1.64.2] is the last minor release of golangci-lint v1. The next release will be golangci-lint v2."

The repo's current golangci.yaml configuration contains deprecated fields which break when using v2.
This pins the golangci-lint version until we can update the configuration to be compatable with v2.
