_content/doc/pgo: correct sample index requirements
The current requirement is completely wrong. In 1.20, we unconditionally
look at sample index 1, which should either be samples/count or
cpu/nanoseconds (they have the same semantic meaning).
For golang/go#58292 (hopefully in 1.20.1), we are correcting this to
pick the first index. I am omitting describing this slight version
discrepancy due to lack of space, but I could be convinced to add it.
For golang/go#58292

Profiles from alternative source may be used with Go PGO if converted to the [pprof format](https://github.com/google/pprof/tree/main/proto), provided they follow these general requirements:
-* Sample index 0 should be type “cpu” and unit “count”.
+* One of the sample indices should have type/unit "samples"/"count" or "cpu"/"nanoseconds".
* Samples should represent samples of CPU time at the sample location.
