chore: remove java 17 as default version since is redundant

`set -e` aborted build.sh when `podman image rm`/`prune` failed, and
`2>/dev/null` hid the reason, so --remove exited 125 with no output.
Combining --remove --prune also skipped the prune.

Guard the removal with `podman image exists` for a clear "nothing to
remove", drop `2>/dev/null` so podman's reason is visible, and use
`cmd || echo` to warn without aborting. Exit status stays 0 on failure
by design.

+# Custom CA certificates
+
+Place any **additional CA certificates** needed to reach internal HTTPS services
+in this directory, as PEM files with a `.crt` extension:
+
+```text
+certs/
+├── README.md
+├── company-root.crt
+└── company-intermediate.crt
+```
+
+This file also guarantees the directory exists in a fresh clone. The build
+copies `certs/` into the image and runs `update-ca-certificates`, so it fails if
+the directory is missing.
+
+## How they are installed
+
+`Dockerfile` copies this directory to:
+
+```text
+/usr/local/share/ca-certificates
+```
+
+and runs:
+
+```bash
+update-ca-certificates
+```
+
+The resulting system CA bundle is also exposed to Node.js through:
+
+```text
+NODE_EXTRA_CA_CERTS=/etc/ssl/certs/ca-certificates.crt
+```
+
+so both system tools and Node.js applications trust the added certificates.
+
+## Rules
+
+* Certificates are baked in at **build time**. The runtime container does not
+  install certificates from the host, so there is no need to mount this
+  directory into the container.
+* Rebuild after any change:
+
+  ```bash
+  ./build.sh --no-cache --update
+  ```
+
+* Only **public** CA certificates belong here. Never commit private material
+  (`*.key`, `*.p12`, `*.pfx`) — everything matched here is copied into the image
+  verbatim.
+* Files must be PEM encoded and use the `.crt` extension. Any other extension
+  (`.pem`, `.cer`, …) is **silently ignored** by `update-ca-certificates`, so
+  rename it to `.crt`. Convert DER with:
+
+  ```bash
+  openssl x509 -inform der -in cert.der -out cert.crt
+  ```
+
+## Troubleshooting
+
+If a certificate seems ignored, the most likely cause is the extension: only
+files ending in `.crt` are installed. A `.pem` file produces no error and no
+warning, it is simply skipped. Rename it:
+
+```bash
+mv company-root.pem company-root.crt
+```
+
+Otherwise check that the file parses as a certificate:
+
+```bash
+openssl x509 -in company-root.crt -noout -subject -issuer -dates
+```
+
+A build that prints warnings from `update-ca-certificates` means a `.crt` file
+is present but is not valid PEM certificate data.
