Include directive for inner config property classes using $ fails

There are four places in the online user guide with errors like

`Unresolved directive in - include::/home/runner/work/micronaut-core/micronaut-core/build/generated/configurationProperties/io.micronaut.http.server.netty.types.files.FileTypeHandlerConfiguration$CacheControlConfiguration.adoc[]`

It appears to be due to the inner class syntax using $. Occurs in:

- `hostResolution.adoc` include::{includedir}configurationProperties/io.micronaut.http.server.HttpServerConfiguration$HostResolutionConfiguration.adoc[]
- `localeResolution.adoc` include::{includedir}configurationProperties/io.micronaut.http.server.HttpServerConfiguration$LocaleResolutionConfiguration.adoc[]
- `transfers.adoc` include::{includedir}configurationProperties/io.micronaut.http.server.netty.types.files.FileTypeHandlerConfiguration$CacheControlConfiguration.adoc[]
- `threadPools.adoc` include::{includedir}configurationProperties/io.micronaut.http.server.netty.configuration.NettyHttpServerConfiguration$Worker.adoc[]

Start with hostResolution.adoc, localeResolution.adoc, transfers.adoc, and threadPools.adoc, then inspect how the generated configurationProperties includes are resolved during the documentation build. Confirm the four unresolved directives and determine how inner-class paths containing $ are handled; done means all four guide pages build without unresolved include errors.
