Update Ktor and logback to mitigate security risks

[johnaziz57]

Proposed Changes

We are trying to adopt Maestro in our company, but running a security scan -using Sonatype IQ server- we found the following issues

1. Ktor 2.2.2, should be updated to 2.3.5
2. Logback 1.2.3, should be updated to 1.2.6

[ERROR] The IQ Server reports policy failing due to 
Policy(Security-High-9) [

There is one more security issue, but unfortunately, I don't have a fix for it yet.

In this PR, I am updating those dependencies.

Update

Ktor 2.3.5 requires minimum Kotlin version of 1.9.0. Ktor 2.3.6 requires minimum Kotlin version of 1.8.0 (Based on what I understood here). So I updated Ktor to 2.3.6 and Kotlin to 1.8.0

Testing

Ran ./gradlew :maestro-test:test and it succeeded Ran ./gradlew installDist and it succeeded

Issues Fixed
