This adds docs for all of ESQL's aggregation functions. Hopefully from here on out we can add the docs as we add new functions. I've created a few tagged regions in the aggs docs themselves so we can include them into the ESQL docs. --------- Co-authored-by: Abdon Pijpelink <abdon.pijpelink@elastic.co>

=== `MEDIAN`
|
|
The value that is greater than half of all values and less than half of
|
|
all values, also known as the 50% <<esql-agg-percentile>>.

NOTE: Like <<esql-agg-percentile>>, `MEDIAN` is <<esql-agg-percentile-approximate,usually approximate>>.

====
|
|
`MEDIAN` is also {wikipedia}/Nondeterministic_algorithm[non-deterministic].
|
|
This means you can get slightly different results using the same data.
