[fix] correct typos / wrong descriptions / stray markdown in SQL data-type
and aggregate-function docs (#3705)
## Summary
Fixes ten small documentation issues across `sql-manual/basic-element/`
and `sql-manual/sql-functions/aggregate-functions/`. Each item below is
independent.
- **STRING.md** — drop the spurious `STRING (M)` from the type
description (both the frontmatter description and the body). STRING does
not take a length parameter.
- **variables.md** — the `version_comment` row showed different values
in the Value vs Default_Value columns (`doris0.0.0--de61c5823` vs
`doris-0.0--de61c5823`). Both columns now use the canonical
`doris-0.0.0--de61c58223` form already used in the zh-CN translation.
- **ai-agg.md** — typo `default_ai_resoure` → `default_ai_resource`.
- **array-agg.md** — remove a stray `| 1 | ["a","b"] |` table row that
sat outside the closing code fence and rendered as literal text.
- **bitmap-intersect.md** — collapse two consecutive `## Example`
headings into one.
- **bool-or.md** — the Return Value paragraph said "TRUE when all
non-NULL values exist", which is the logical AND semantics. Corrected to
"TRUE when at least one non-NULL value is TRUE".
- **covar-samp.md** — remove an orphan duplicated result-table block
plus an extra closing code fence that appeared after the legitimate one.
- **histogram.md** — the `lower` and `upper` bucket field descriptions
were swapped (`lower: Upper bound`, `upper: Lower bound`). Corrected.
- **JSON.md** — two consecutive bullets both began with `CAST(string AS
JSON):`. Merged into one bullet that keeps the content of both.
- **percentile_reservoir.md** — the third example's query and result
header used `percentile(...)` instead of `percentile_reservoir(...)`
(looked like copy-paste from `percentile.md`).
## Test plan
- [ ] CI doc build passes
- [ ] Spot-check the affected pages render as expected (STRING.md
description, variables.md `version_comment` row, single `## Example` in
bitmap-intersect, clean result tables in array-agg / covar-samp,
corrected bucket field descriptions in histogram, merged bullet in
JSON.md, `percentile_reservoir` in the third example)

Int32, Int64, Int128, and Double types, not Decimal type.
+- CAST(string AS JSON): Used to parse strings that conform to JSON syntax. For
Number types, it will only parse Int8, Int16, Int32, Int64, Int128, and Double

- Unlike most other JSON implementations, Doris's JSONB type supports up to
Int128 precision. Numbers exceeding Int128 precision may overflow.
- If the input number string is 12.34, it will be parsed as a Double; if
there's no decimal point, it will be parsed as an integer (if the size exceeds
Int128 range, it will be converted to Double but with precision loss)

### Description
-STRING (M)
A variable length string. Default support is 1048576 bytes (1M), adjustable up
to 2147483643 bytes (2G),and the length of the String type is also limited by
the configuration string_type_length_soft_limit_bytes(a soft limit of string
type length) of be. the String type can only be used in the value column, not
in the key column and the partition and bucket columns
Note: Variable length strings are stored in UTF-8 encoding, so usually English
characters occupies 1 byte, and Chinese characters occupies 3 bytes.
