A clear and concise description of what the bug is.

Affected version

Please run docker run -i --rm ghcr.io/github/github-mcp-server ./github-mcp-server --version and paste the output below

Steps to reproduce the behavior

1. Run golangci-lint run with golangci version >= 2.

Expected vs actual behavior

Failed executing command with error: can't load config: can't unmarshal config by viper (flags, file): 1 error(s) decoding:

* 'output.formats' expected a map, got 'string'

Logs

I'm trying to setup the project in my local machine by going through the CONTRIBUTING guide. And running golangci-lint run returns this error.

I noticed that the .golangci.yml was migrated to the latest config. Is migrating the config is the right thing to do?

golangci-lint version 2 is only 6 weeks old or so (https://github.com/golangci/golangci-lint/releases/tag/v2.0.0) and we haven't updated our CI from version 1 (https://github.com/github/github-mcp-server/blob/e56c096e398faf9cf49f528816c208d931f9d834/.github/workflows/lint.yaml)

I would welcome a PR that fixes this, and updates our CI and documentation to require golangci-lint version 2.
