fix(plugins): restore the main build after #3205 and #3208 changed the same cell text API

[datlechin]

main does not build its test target. #3205 and #3208 both reworked how Elasticsearch, Typesense and SurrealDB turn a value into cell text, were each green on their own branch, and landed one after the other:

• fix(plugins): keep long arrays and objects whole in Elasticsearch, Typesense and SurrealDB table exports #3205 added a length parameter (.display for the grid, .whole for exports) to ElasticsearchMappingFlattener.cell, TypesenseSchema.cell and SurrealDB's text(_:).
• fix(plugins): refuse saving an Elasticsearch, Typesense or SurrealDB value shortened for display #3208 added tests that call the two cell functions without it, and replaced SurrealDB's jsonText(_ length:) with a jsonText property that always truncates.

The result on main:

TypesenseDriverTests.swift:967:64: error: missing argument for parameter 'length' in call
SurrealValue+Display.swift:36:20: error: cannot call value of non-function type 'String'

Changes

• SurrealValue.jsonText(_ length:) is back, with fix(plugins): refuse saving an Elasticsearch, Typesense or SurrealDB value shortened for display #3208's JSONTruncation.truncate for .display and the whole JSON for .whole, the same shape as TypesenseSchema.serializeJson. Exports keep long arrays and objects whole (fix(plugins): keep long arrays and objects whole in Elasticsearch, Typesense and SurrealDB table exports #3205's intent), and the grid keeps the truncation fix(plugins): refuse saving an Elasticsearch, Typesense or SurrealDB value shortened for display #3208 relies on to refuse saving a shortened value.
• The three test helpers from fix(plugins): refuse saving an Elasticsearch, Typesense or SurrealDB value shortened for display #3208 (displayed(_:), shortenedAuthors(), and the shown part in updateRefusesACompleteArrayWrittenOverAShortenedOne) pass length: .display, which is what they are named for.

No CHANGELOG entry: both PRs are unreleased and their entries already describe the behaviour.

Verification

• All 22 Elasticsearch, Typesense and SurrealDB test types: 225 passed.
• SwiftLint on the three files: 0 violations.
