Fix K8S_AUTH_VERIFY_SSL environment value handling in kubectl connection plugin (#1049)

Browse Source 
SUMMARY
Fixed a bug where setting K8S_AUTH_VERIFY_SSL=true (or any string value) caused the value to be treated as a separate kubectl command argument instead of being properly converted to a boolean.
The option key name is validate_certs, which does NOT end with "verify_ssl", so the original condition key.endswith("verify_ssl") at line 327 failed. This caused the code to fall through to the else block which added the value as separate
arguments: ["--insecure-skip-tls-verify", "true"], making "true" appear as a kubectl command.
Fixes #1021
ISSUE TYPE

Bugfix Pull Request

COMPONENT NAME
kubernetes.core.kubectl
ADDITIONAL INFORMATION
Changes Made

Changed condition from key.endswith("verify_ssl") to key == "validate_certs"
Added import of boolean function from ansible.module_utils.parsing.convert_bool
Added proper boolean conversion using boolean(self.get_option(key), strict=False)

Partially used LLM (GitHub Copilot with Claude Sonnet 4).
Before Fix
K8S_AUTH_VERIFY_SSL=true
Command: ['/usr/bin/kubectl', '--insecure-skip-tls-verify', 'true', 'exec', ...]

                                                            ^^^^^ treated as kubectl command (BUG!)

After Fix
K8S_AUTH_VERIFY_SSL=true
Command: ['/usr/bin/kubectl', '--insecure-skip-tls-verify=false', 'exec', ...]
                                                           ^^^^^ properly converted (FIXED!)
