Fix compileTruncate return type and SQL typo.

[calmdev]

The method annotation expects an array to be returned. The SQL executed by the method also had a typo.

We're seeing this issue on a 1.2.x tagged release, but still seems relevant in main. Any chance we can have this patch back-ported to those earlier releases using an older version of illuminate/database?

Return Type Issue

Reproduce:

// Truncate a model using a snowflake connection
Country::on('snowflake')->truncate();

Result:

Psy Shell v0.11.15 (PHP 8.2.28 — cli) by Justin Hileman
> Country::on('snowflake')->truncate();

   WARNING  foreach() argument must be of type array|object, string given in vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php on line 3585.

= Illuminate\Database\Eloquent\Builder {#8554}

Solution:

Return an array to fix the warning.

SQL Typo Issue

Reproduce (after fixing previous issue):

// Truncate a model using a snowflake connection
Country::on('snowflake')->truncate();

Result:

Psy Shell v0.11.15 (PHP 8.2.28 — cli) by Justin Hileman
> Country::on('snowflake')->truncate();

   Illuminate\Database\QueryException  SQLSTATE[42000]: Syntax error or access violation: 1003 SQL compilation error:
syntax error line 1 at position 0 unexpected 'trunate'. (Connection: snowflake, SQL: trunate table "countries").

Solution:

Replace typo `trunate` with `truncate`.
