Update lint-project.sh

[alovak]

The lint-project.sh script currently runs golangci-lint in two separate instances. Initially, it's executed with all linters turned off except for forbidigo (see reference). Following this, it is run again, this time with all linters enabled except for forbidigo (see reference).

To bypass the forbidigo linter for specific files that utilize panic, the //nolint directive was used. This directive was effective only during the first instance of the linting process. However, during the second linting round, the //nolint directive becomes superfluous since forbidigo is not active. This redundancy leads to the detection of an unused nolintlint directive error, as illustrated in the following output:

Error: message.go:42:14: directive `//nolint // as specs moslty static, we panic on spec validation errors` is unused (nolintlint)
		panic(err) //nolint // as specs moslty static, we panic on spec validation errors

With this PR, we introduce the GOLANGCI_ALLOW_PANIC environment variable. When it's set to yes, no checks for panic are performed by forbidigo. It's done similarly to GOLANGCI_ALLOW_PRINT.

P.S. it's not a viable option to remove panic from https://github.com/moov-io/iso8583/ (see moov-io/iso8583#269)

This //nolint:forbidigo,nolintlint helped me. No need in the PR.
