Update "golangci-lint" to 2.3

Support for "golangci-lint" 1.x was dropped starting from version 7.0.0 of the "golangci/golangci-lint-action" GitHub
Actions action. The version of "golangci-lint" used by the "Check Go" GitHub Actions workflow is hereby updated to
2.3.x.

Changes to the asset "golangci-lint" configuration file were required to accommodate the bump to 2.x:

* Addition of `version` key.
* Removal of `issues.exclude-use-default` key.

The latter is no longer supported because the "golangci-lint" finally came to their senses and stopped disabling
arbitrary rules by default. Disabling of rules is now only done when explicitly configured. Since the
`issues.exclude-use-default` key in the asset was used only to enable the rules that "golangci-lint" 1.x disabled by
default, the equivalent configuration for "golangci-lint" 2.x is achieved by simply removing this key from the
configuration file.
