Create 13_edb_audit_nested_statements

[yuki-tei]

Hi,
Greetings. Hope you are doing well and healthy.

What Changed?

Added the page for below enhancement in EPAS 18.1.
https://www.enterprisedb.com/docs/epas/latest/epas_rel_notes/epas18_1_rel_notes/

Enhancement | Added support to audit nested statements to edb_audit. We've enhanced database security by implementing nested statement audit logging. A new configuration parameter, edb_audit_nested_statements, allows administrators to capture statements executed within functions and procedures. This enhancement ensures complete audit trails, effectively preventing malicious users from bypassing security logs through hidden code execution. -- | --

The new page is described based on below:

edb=# SELECT * FROM pg_settings WHERE name = 'edb_audit_nested_statements';
-[ RECORD 1 ]---+-------------------------------------------------------------------------------------
name            | edb_audit_nested_statements
setting         | off
unit            |
category        | EnterpriseDB Auditing Settings
short_desc      | Enable audit logging for the nested statements.
extra_desc      | When enabled, nested statements are audit logged along with the top level statement.

boot_val        | off
reset_val       | off
sourcefile      |
sourceline      |

Please take a look and see if it is correct.
