[DOCS] Querying basics: explain range and instant queries
...
I often see people ask questions that indicate they don't understand
this point, and launching into "instant vector" and "range vector" is
likely to point them in the wrong direction.
Remove the admonishment that the reader mustn't confuse these things.
Remove mention of "inferred sample timestamps" that is never explained.

PromQL: Always enable negative offset and @ modifier
...
This follows the line of argument that the invariant of not looking
ahead of the query time was merely emerging behavior and not a
documented stable feature. Any query that looks ahead of the query
time was simply invalid before the introduction of the negative offset
and the @ modifier.

'@ <timestamp>' modifier ( #8121 )

This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit .
An example query:
```
rate(process_cpu_seconds_total[1m])
and
topk(7, rate(process_cpu_seconds_total[1h] @ 1234))
```
which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.
