Trivial minor issue | A confirmation log of having written successfully the dns cache ttl setting in JVM setting file must get printed only after it has successfully done so and not before.

Issue: Confirmation Log Order

https://github.com/paketo-buildpacks/libjvm/blob/main/helper/link_local_dns.go#L54
In the Execute function of the LinkLocalDNS type, the log message indicating that JVM DNS caching has been disabled is printed before the function has successfully written the changes to the JVM settings file. The confirmation log should only be printed after successfully writing to the file.

Expected Behavior

The confirmation log message should only be printed after the DNS settings have been successfully written to the file. If an error occurs while opening or writing to the file, the function should not log the confirmation message and should instead return an appropriate error.

Current Behavior

The function logs l.Logger.Info("JVM DNS caching disabled in favor of link-local DNS caching") before ensuring that the DNS settings have been correctly written to the specified file. This log message may appear even if the file write operation fails.
