[MBL-1915] Fix Content Hugging and Compression in PledgeDisclaimerView.iconImageView

[jovaniks]

📲 What

Fixes alignment issues for the iconImageView in PledgeDisclaimerView by setting appropriate content hugging and compression resistance priorities.

🤔 Why

The iconImageView displayed inconsistent alignment on the checkout screen due to:

Variations in the "Kickstarter is not a store" text content.
Differences in the checkout screen components rendered.
Changes in the os language, which altered text length based on translations.
This fix ensures consistent alignment of the iconImageView across all scenarios.

🛠 How

Updated constraints for the iconImageView in setupConstraints:

private func setupConstraints() {
   self.iconImageView.setContentHuggingPriority(.required, for: .horizontal)
   self.iconImageView.setContentCompressionResistancePriority(.required, for: .horizontal)
}

Ensures that the iconImageView maintains its alignment regardless of the text length, screen components, or system language.
