Make regex-matching docs more obvious
Split out the note about regex-matching into a separate paragraph to
make it more obvious. Move it up, closer to the definition.

beorn7 b39f2739e5 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.

Semyon Slepov 33f085a4d6 Remove bits about substring matching from the docs (#5549)
Substring matching for labels doesn't work anymore.
These parts are misleading, and contradict with the rest of the
documentation.

Matthias Rampke cae4538b3e Docs: state that all regular expressions are RE2. (#3518)
We already mentioned that regular expressions are RE2 for
[relabeling][0], but left open what the regular expression syntax
anywhere else is.

In the querying examples and reference, make it explicit that _all_
regular expressions are RE2.
