[KYUUBI #7160] Use single try-with-resources blocks in docs example

Browse Source 
Gets rid of the nested try-with-resources blocks. Improves legibility slightly.

### Why are the changes needed?
Make the example code just a bit nicer.

### How was this patch tested?
It still compiles. I created a simple (maven) project using only these two java files.

### Was this patch authored or co-authored using generative AI tooling?
No

Closes #7160 from jagij/patch-1.
