Workhorse error handling in deferred functions

Problem

golangci linter complains about lack of verification for errors in deferred functions.

Error return value of `content.Close` is not checked (errcheck)

During the refactoring this problem was addressed in several ways:

1. Log an error in defer function

defer func() {
    if err = content.Close(); err != nil {
        fmt.Printf("Error closing file: %v", err)
    }
}()

source

2. Ignore the error

defer func() { _ = body.Close() }()

source

Currently, the codebase includes both options.

Proposal

1. Discuss and define how should we handle this case
2. Document the decision
3. Unify codebase to follow the same approach
4. Try to enforce it via golangci (if possible)
