doc: clarify filter option of sqlite.database.applyChangeset

[aduh95]

The current version is quite confusing, if not plain wrong. I was heavily inspired by https://sqlite.org/session.html#sqlite3changeset_apply for that change.

For reference, our xFilter is implemented in

node/src/node_sqlite.cc

Lines 2238 to 2242 in 89c414a

	static int xFilter(void* pCtx, const char* zTab) {
	auto ctx = static_cast<ConflictCallbackContext*>(pCtx);
	if (!ctx->filterCallback) return 1;
	return ctx->filterCallback(zTab) ? 1 : 0;
	}

Maybe we should update to sqlite3_changeset_apply_v3. It has less confusing behavior it looks like.

I have no opinion, but in any case we probably want to land the doc fix ASAP
