  1. docs: document self-signed certificate / internal CA handling for Git… 

    …Hub Enterprise

Adds an advanced-usage section explaining the 'self signed certificate in
certificate chain' error seen on GitHub Enterprise Server and behind
TLS-inspecting proxies. Recommends the secure fix of trusting the internal
CA via NODE_EXTRA_CA_CERTS (or the OS trust store on self-hosted runners),
with a GitHub Enterprise callout, and warns against disabling TLS
verification since the JDK download has no checksum fallback.

  2. docs: add post-install keytool import for the JDK cacerts trust store 

    Document how to make the installed JDK trust an internal CA at application
runtime by importing it into $JAVA_HOME/lib/security/cacerts with keytool
after setup-java runs. Clarifies this is the runtime trust layer, distinct
from the download/transport layer (NODE_EXTRA_CA_CERTS), and notes hosted vs
self-hosted persistence caveats.
