{{now.weekOfYear}} returns the wrong week number

When now.weekOfYear is used in A4J rules, it returns the wrong week number

Steps to Reproduce

1. Create an automation rule to create a ticket in a project
2. In the Create issue event, include now.weekOfYear in the summary
3. Execute the rule and check the week number in the issue summary

Expected Results

now.weekOfYear should return the correct week number

Actual Results

now.weekOfYear returns the wrong week number

Example:
In the screenshots attached, the log-action shows week 9 but we are in week 8 (Feb 22 - Feb 28) of 2021

Workaround

There're different ways to count the week of the year (see Week numbering), so, due to that, on Automation for Jira 7.3.3 (Release notes) a new Smart Value was added to differ both weeks count compliant:

• ISO compliant

  {{now.weekOfYearIso}}

• Classic compliant

  {{now.weekOfYear}}

With that said, use the ISO compliant, then you should get the expected week count.
