Pull Request Overview
This PR introduces a mechanism to warn users when the target module's Go version is below 1.22 for the std-http-server generation, helping avoid runtime issues such as unexpected 404 responses. Key changes include:
- Adding functions to locate and parse go.mod/tools.mod files and verify the Go version.
- Implementing warning generation in GenerateOptions and integrating warning output in the CLI.
- Updating the main command to display warnings when present.

On non-Unix systems, using a hard-coded "/" as the root directory may lead to improper behavior; consider using a cross-platform approach to determine when to stop recursing upward.

Although this is less necessary after bumping our minimum Go version to 1.22 (in 0e8156a), it's still worthwhile ensuring that the module we're generating the code for is correctly set to Go 1.22, otherwise users will receive: HTTP/1.1 404 Not Found ... 404 page not found To do this, we can introduce a new means to flag "warnings" that need to be output. We need to make sure we're using `ParseLax` to reduce the risk of new directives or content being introduced into a `go.mod` breaking `oapi-codegen`. This is a step towards being able to implement future warnings to ensure that consumers are using correct Go versions. Closes #1628. [0]: https://www.jvt.me/posts/2024/03/04/go-net-http-why-404/
