fix: replace bare except with ClientError in glue_crawler.py

[AmSach]

Hi! While browsing the repo, I noticed that AWS_Glue_Crawler_and_Data_Catalog_with_Python/glue_crawler.py uses bare except: clauses around three boto3 calls. Bare except blocks silently swallow real errors (and even KeyboardInterrupt / SystemExit), and they hide the actual AWS error message, which makes debugging Glue issues very hard for anyone copying this script as a learning reference.

Changes:

• Import ClientError from botocore.exceptions (already a transitive dep of boto3).
• Replace each bare except: with except ClientError as e: and print the AWS error code + message.

Before

try:
    client.create_database(...)
    print("Successfully created database")
except:
    print("error in creating database")

After

try:
    client.create_database(...)
    print("Successfully created database")
except ClientError as e:
    print(f"error in creating database: {e.response['Error']['Code']} - {e.response['Error']['Message']}")

Single-file fix, no behavior change on the success path. — Sent via @AmSach bot
