refactor: replace parse-duration with ms

[dev-737]

The changes replace the parse-duration library with ms for parsing duration strings in the blacklist handler and related commands. This simplifies the code and provides a more consistent way of handling duration inputs.

The main changes include:

• Replacing parse(interaction.fields.getTextInputValue('duration')) with ms(interaction.fields.getTextInputValue('duration')) in the getModalData method of the BaseBlacklistHandler class.
• Replacing parse(cooldown, 'hour') with ms(cooldown) / 1000 / 60 / 60 in the handleAppealCooldown method of the AppealCommand class.
• Replacing parse(expiryStr) with ms(expiryStr) in the Invite command class.
• Replacing parse(expiryStr) with ms(expiryStr) in the ServerBlacklist command class.

These changes improve the overall consistency and maintainability of the codebase.
