Simplify estimated label text

[KJhellico]

Proposed change

Now estimated holidays look like "Eid al-Fitr* (*estimated)". Usually this style is used for footnotes at the end of text or page. In our case, the explanation goes directly after the text. Therefore, I propose to remove the asterisk (similar to the label for observed holidays) - "Eid al-Fitr (estimated)".

Type of change

• New country/market holidays support (thank you!)
• Supported country/market holidays update (calendar discrepancy fix, localization)
• Existing code/documentation/test/process quality improvement (best practice, cleanup, refactoring, optimization)
• Dependency update (version deprecation/upgrade)
• Bugfix (non-breaking change which fixes an issue)
• Breaking change (a code change causing existing functionality to break)
• New feature (new python-holidays functionality in general)

Checklist
