feat: add support for insecure mode in Gitea client configuration (#20)

- Add `GITEA_INTERACTIVE` configuration example in README files
- Add `insecure` flag to ignore TLS certificate errors in `cmd.go`
- Set insecure mode based on `GITEA_INSECURE` environment variable in `cmd.go`
- Add `Insecure` boolean variable in `pkg/flag/flag.go`
- Import `crypto/tls` and `net/http` in `pkg/gitea/gitea.go`
- Modify Gitea client creation to support insecure HTTP client in `pkg/gitea/gitea.go`
