battle_tag_check fails to validate correctly formatted battle tag

[ColeMundus]

Describe the bug
The battle_tag_check method in the Overwatch class incorrectly restricts the battletag ID to only 4 or 5 digits. Overwatch player IDs can sometimes be 6 digits long, so this validation fails for valid battletags with 6-digit IDs.

To Reproduce
Steps to reproduce the behavior:

• Call the all_player_data method with a battletag that has a 6-digit ID, e.g., ExampleUser#123456.
• Observe that the method fails to validate this correctly formatted battletag.

Expected behavior
The method should correctly validate battletags with IDs that are 4, 5, or 6 digits long. Battletags such as ExampleUser#123456 should be recognized as valid.

The regular expression used in the battle_tag_check method is r"^[a-zA-Z0-9]{3,12}#[0-9]{4,5}$". This should be updated to r"^[a-zA-Z0-9]{3,12}#[0-9]{4,6}$" to accommodate battletags with 6-digit IDs.
