Function buildRoute53DnsConfig

buildRoute53DnsConfig(
options?: Route53DnsProviderConfig,
): AcmeDnsProviderConfigResult
Build the caddy-dns/route53 config.

Called with no options (the default), caddy-dns/route53 reads credentials via the AWS Go SDK v2's own default credential chain (env vars, shared profile, or IAM role) — providerConfig is omitted rather than reimplementing that resolution, exactly as before 0.9.0.

The plugin also supports an explicit typed providerConfig (real, verified Go source — see Route53DnsProviderConfig) for callers who want it instead of relying on ambient credentials: pass any subset of fields via options and they're returned as providerConfig.
Parameters
- Optionaloptions: Route53DnsProviderConfig
Returns AcmeDnsProviderConfigResult
Example
```
buildRoute53DnsConfig()
// => { envVars: ["AWS_ACCESS_KEY_ID", "AWS_SECRET_ACCESS_KEY", "AWS_REGION"] }
```
Example
```
buildRoute53DnsConfig({ hosted_zone_id: "Z1D633PJN98FT9", region: "us-east-1" })
// => { providerConfig: { hosted_zone_id: "Z1D633PJN98FT9", region: "us-east-1" }, envVars: [...] }
