LogcatAppender show errors for logs' "highlighting".

[LSmyrnaios]

Describe the bug

Hi,

I have set the LogcatAppender as such:

<appender name="Logcat" class="ch.qos.logback.classic.android.LogcatAppender">
        <encoder>
            <charset>UTF-8</charset>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %highlight(%-5level) %cyan(%logger{36}.%M\(@%line\)) - %msg%n</pattern>
        </encoder>
    </appender>

Wehn running the app, I get the following errors:

I/System.out: 13:58:11,249 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@a052b99 - There is no conversion class registered for composite conversion word [highlight]
I/System.out: 13:58:11,249 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@a052b99 - Failed to create converter for [%highlight] keyword
I/System.out: 13:58:11,249 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@a052b99 - There is no conversion class registered for composite conversion word [cyan]
I/System.out: 13:58:11,249 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@a052b99 - Failed to create converter for [%cyan] keyword

When using the "ConsoleAppender", in non-android projects, with the aforementioned pattern, the logs get highlighted.

Could you please add support for logs-highlighting?

Thank you

Reproduction

Set the above pattern inside the LogcatAppender, run the app and check the Logcat output for errors.
