[mysql] Fix SQL_TABLES query to use single quotes for ANSI_QUOTES compatibility (DataDog#23593)

* Fix quotes in SQL query for TABLE_TYPE

Reference: DataDog#23590

Use single quotes

Description
The SQL_TABLES query in mysql/datadog_checks/mysql/queries.py uses double quotes for the string literal "BASE TABLE":

When sql_mode includes ANSI_QUOTES, MySQL interprets "BASE TABLE" as an identifier (column name) rather than a string literal, causing:

```
SQL_TABLES = """\
SELECT table_name as `name`,
       engine as `engine`,
       row_format as `row_format`,
       create_time as `create_time`
       FROM information_schema.TABLES
       WHERE TABLE_SCHEMA = %s AND TABLE_TYPE="BASE TABLE"
"""

```

When sql_mode includes ANSI_QUOTES, MySQL interprets "BASE TABLE" as an identifier (column name) rather than a string literal, causing:

> pymysql.err.OperationalError: (1054, "Unknown column 'BASE TABLE' in 'where clause'")

Fix
Replace double quotes with single quotes:
> WHERE TABLE_SCHEMA = %s AND TABLE_TYPE='BASE TABLE'

Environment
Agent version: 7.77.3
Aurora MySQL 8.0 with ANSI_QUOTES in sql_mode
Feature: collect_schemas: enabled: true
