[23a2a8] Image has non-empty accessible name

Hello ACT rules,

This is a call for review to update the rule "[23a2a8] Image has non-empty accessible name." The proposed changes adds an important acc support note since popular browsers are all treating images differently, and removes the inapplicable example 1.
PR: https://github.com/act-rules/act-rules.github.io/pull/2290

Call for review ends on February 28th 2025.
