Update `Path` creation for nested locations to allow both UNC and classic
file references to be used. This commit attempts to align our URL
handling with that of standard file URLs. The `NestedLocation` class
no longer attempts to remove leading all `\` characters and instead
only removes the first `\` when the second char is `:`. This duplicates
the logic found in Java's own internal `WindowsUriSupport` class which
is used when calling `Path.of(url)` with a `file:` URL.

In order to support Java 22, we must use spring-core 6.1.x.
spring-core 6.1.x is a multi-release jar so, in order to support Java
22, a version of Gradle that supports multi-release jars must be
used.
This commit adds a new variant to spring-boot-gradle-plugin for
modern versions of Gradle. When Gradle's plugin API version is 8.7 or
later, we use spring-core 6.1.x. spring-core 6.0.x is used at all
other times.

Fix regression in `JarUrlConnection` where a NullPointerException could
be thrown internally causing performance issues.

thrown:

Update buildpack support to allow gzip compressed image layers to be
used when returned by the Docker engine. This update is restores
buildpack support when using Docker Desktop with the "Use containerd
for pulling and storing images" option enabled.
This commit introduces a new `ExportedImageTar` class to deal with the
intricacies of determining the mimetype of a layer. The class deals with
the parsing of `index.json' and related manifest blobs in order to
obtain layer information. The legacy `manifest.json` format is also
supported should `index.json` be missing.
Tests have been added to ensure that export archives from Docker Engine,
Docker Desktop (with and without containerd), and Podman can be used.
Fixes gh-40100
