ESQL: Generate a few more docs (#106577) And improve the error message on csv test failures.

// This is generated by ESQL's AbstractFunctionTestCase. Do no edit it. See ../README.md for how to regenerate it.
ESQL: Generate more docs (#106367) This modifies the ESQL test infrastructure to generate more of the documentation for functions. It generates the *Description* section, the *Examples* section, and the *Parameters* section as separate files so we can use them as needed. It also generates a `layout` file that's just a guess as to how to render the whole thing. In some cases it'll work and we can use that instead of hand maintaining a "top level" description file for the function. Most newly generated files are unused. We have to chose to pick them up by replacing the sections we were manually maintaining with an include of the generated section. Or by replacing the entire hand maintained file with the generated top level file. Relates to #104247

*Description*
ESQL: extend BUCKET with spans. Turn it into a grouping function (#107272) This extends `BUCKET` function to accept a two-parameters-only invocation: the first parameter remains as is, while the second is a span. It can be a numeric (floating point) span, if the first argument is numeric, or a date period or time duration, if the first argument is a date. Also, the function can now be invoked with the alias BIN. Additionally, the function has been turned into a grouping-only function and thus can only be used within a `STATS` command.

Creates groups of values - buckets - out of a datetime or numeric input. The size of the buckets can either be provided directly, or chosen based on a recommended count and values range.
