upgrade to logback 1.3.5 (slf4j 2)

[Sokrim]

Since my previous PR #51 has been merged but logback version 1.4.5 is for Java 11, now I submit another PR using logback version 1.3.5 which is for Java 8. This will fix the issue https://github.com/j256/cloudwatch-logback-appender/issues/50

Any chance this can be merged and released soon? Spring Boot (3) is now on 1.4.5 and incompatible out-of-the-box with current cloudwatchlogbackappender 2.1.

Not only is 1.4.x meant for Java 11, it is intended for users that have moved on to the Jakarta namespace. Keeping to 1.3.x seems to be the way to go. I second bacherma's question regarding a release for this?

Additionally, the Logback website states: "Logback components written for logback 1.2 should work without change in version 1.3."

Hi, is it possible appender can support logback 1.3.5?

Hey @bacherma did you manage to use the appender with Spring Boot 3? If so, can you describe what you did?
