Add linter for Temporal interface

[AskAlexSharov]

1. find existing linter (in golnagcilint) which will catch such things: https://github.com/erigontech/erigon/pull/13120/files (i'm sure it exists).
2. add in rules.go match for BeginTemporalRo (and rw).

added nilness linter - #13146
it doesn't do alingse's nilnesserr; should we wait for alingse to add it to golanci-lint? Same option is not present. @AskAlexSharov

I mean to catch the issue like https://github.com/erigontech/erigon/pull/13120/files, we need the new nilnesserr linter, which is still in development and not added to golangci-lint. The author said it'll be added once testing is done.

Meanwhile, I added the nilness linter in this PR. It catches redundant patterns like if err != nil where err is always nil or err. But doesn't catch more advanced errors like nilnesserr.
