Update ktlint to 1.x

[TobiGr]

Problem

ktlint is currently failing our vulnerability / snyk pipelines. One of its dependencies is vulnerable (CVE-2023-6378). This has no implications on NewPipe itself, because ktlint is used to format code while developing.

Upgrading ktlint is easy and requires following changes:

• within build.gradle: ktlint 'com.pinterest:ktlint:0.45.2' -> ktlint 'com.pinterest.ktlint:ktlint-cli:1.x.x'
• Adapting Kotlin code to current style guides:
  • Rename: org.schabi.newpipe.info_list -> org.schabi.newpipe.infoList
  • Fix some variable naming schemes

The problem is that all Kotlin files are going to be reformatted which causes merge conflicts with all PRs touching Kotlin code

Proposed solution

Wait with upgrade until most PRs are merged, update it before starting the rewrite
