Documents the index.load_fixed_bitset_filters_eagerly setting.

Context

Prior to 2.3, users would frequently set index.load_fixed_bitset_filters_eagerly to false to avoid memory errors for mappings containing a large number of nested fields.

The need for that workaround was largely reduced in 2.3+ with #15989. That PR introduced index.mapping.nested_fields.limit which limits the number of nested fields. For that reason, I avoided referencing the workaround or other heuristics in this definition.

@jrodewig Thanks for updating documentation. Would you mind to backport this change to earlier versions as well (at least 5.6 and 6.7). We had an SDH issue where people were wondering if this setting is available in earlier versions as well.
