This is a linux-only assertion to guard against file descritor leaks.

Unlike goroutine leak checks, this one does not support parallel tests.

tests: skip testable examples for NoFileDescriptorLeak on windows/macos

* feat(condition): added support for Consistently
* feat(condition): added support for func(context.Context) error to async assertions Eventually and Consistently

> NOTE: refrained from adding func(ctx) error to Never,
> as it introduces a confusing logic which is awkward to document and prone to errors.

**BREAKING**: removed Condition type - no value added to alias func() bool

> Part of our plan to clean up unnecessary extra types

chore: removed bash script for local testing with hugo (now a go "script")

> Part of our plan to superseded all local bash by go scripts.
> Bash has a place and it's in CI only.
