[doc] cover the native collector packages in the release guide

[Duansg]

What's changed?

The release guide signs and checksums artifacts with:

for i in *.tar.gz; do ... done

Since 1.9.0 the release also contains *-windows-amd64-bin.zip, which that glob does not match. The shell skips it without any error, so the Windows native collector package went into the 1.9.0-RC2 vote with no .asc and no .sha512 — a -1 under the ASF release policy.

Changes

• match *.zip in both loops
• skip artifacts that already have a signature or checksum, so re-running the step does not re-sign artifacts that are already published
• list the three native collector packages in the expected dist contents

Both the English and the Chinese version of the guide are updated.
