[Native Image] Trivial typo: `reachability-metadata.json` not `reachability-metadata.md`

[edburns]

Describe the Issue

Consider this message:

Warning: Option 'DynamicProxyConfigurationResources' is deprecated and might be removed in a future release: 
This can be caused by a proxy-config.json file in your META-INF directory. Consider including proxy configuration 
in the reflection section of reachability-metadata.md instead.. Please refer to the GraalVM release notes.

I am pretty sure the file is reachability-metadata.json not reachability-metadata.md.

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.
