fix: ignore cache error when file not found

[ldez]

Inside Go this error is ignored.

https://github.com/golang/go/blob/239dbd7dbac883d6f9b6522774a0dfd519f77fa8/src/cmd/go/internal/cache/cache.go#L288

As I explained inside #5098:

The main modifications are about error handling: the official Go cache implementation ignores many errors, and the implementation inside Golangci-lint reports those "hidden" errors.

We should convert this error to an entryNotFoundError error, then the error will be "ignored".

Before this PR, something like that can happen:

It just a warning and it doesn't impact the behavior of golangci-lint but those logs are useless.
