feat: added validator version to report filename

[cka-y]

Summary:
Closes #401
This PR updates the naming convention of validation reports to include the validator version. This change affects both HTML, JSON report and system_errors.json name formats and the corresponding updates have been made in the database update process to reflect this new naming convention.

Expected Behavior:
With the changes introduced in this PR, the filenames for both HTML and JSON validation reports will now include the validator version, ensuring clearer traceability and management of report files across different validator versions.

Database Example:
Below is an example from the ValidationReport entity for feed mdb-101 demonstrating how the reports are named with the validator version included:

id	validator_version	validated_at	html_report	json_report
mdb-101-202404010645_5.0.2-SNAPSHOT	5.0.2-SNAPSHOT	2024-04-24 15:25:07+00	https://dev-files.mobilitydatabase.org/mdb-101/mdb-101-202404010645/report-5.0.2-SNAPSHOT.html	https://dev-files.mobilitydatabase.org/mdb-101/mdb-101-202404010645/report-5.0.2-SNAPSHOT.json
