Bump ktlint to 0.48.2

[wmontwe]

Fixed the issue with code style setup to allow update of ktlint 0.47.1 -> 0.48.2.

With ktlint 0.48.x, trailing-comma-on-call-site and trailing-comma-on-declaration-site rules have been enabled by default.

This previously caused failures when formatting the Kotlin source code.

With enabling ij_kotlin_allow_trailing_comma and ij_kotlin_allow_trailing_comma_on_call_site rules in .editorconfig and some small manual corrections, ktlint now properly formats.

Notable difference for enum classes:

1. Last entry needs to be a trailing comma
2. If enum class contains members, a semicolon needs to be placed on the next line (better git readability) This is sadly not supported by Intellij IDEA

enum class Type {
    TYPE_1,
    TYPE_2, <-- *1*
    ;   <-- *2*

    fun foo() { ... }
}

Also cleaned up remaining formatting issues for Kotlin sources.
