Please add version string into release metadata

Before it was possible to check if there update required by checking name from release (which actually was a date) and date from --version string. Now this update script is not working because there is no more date reported by --version and no version field in releases.json. So, it would be nice to have the possibility to automatically match installed rust-analyzer binary against available in releases section.

#!/bin/bash
TMP_DIR=$(mktemp -d)
echo "Work in ${TMP_DIR}"
curl -L -H "Accept: application/vnd.github+json" -H "Authorization: Bearer your_secret_ro_token" -H "X-GitHub-Api-Version: 2022-11-28" https://api.github.com/repos/rust-lang/rust-analyzer/releases > ${TMP_DIR}/releases.json

LAST_VER=`jq 'map(select(.prerelease == false)) | first.name ' ${TMP_DIR}/releases.json | tr -d v\"`
CURRENT_VER=$(~/bin/rust-analyzer --version|awk '{print $4}' | tr -d \))
if [[ $LAST_VER != $CURRENT_VER ]]; then
    echo "Versions differs: found last ${LAST_VER} vs old ${CURRENT_VER}"
    URL=`jq 'map(select(.prerelease == false)) | first.assets | map(select(.name=="rust-analyzer-x86_64-unknown-linux-gnu.gz"))[0].browser_download_url ' ${TMP_DIR}/releases.json | tr -d \"`
    cd $TMP_DIR
    wget $URL -O - | zcat - > /tmp/rust-analyzer
    mv /tmp/rust-analyzer ~/bin/rust-analyzer
    chmod +x ~/bin/rust-analyzer
fi

Start with the release metadata represented by releases.json and the rust-analyzer --version output, then trace the release process that produces them. Confirm that a version field is available for matching installed binaries with the latest non-prerelease release, and verify the shell update script can use it.
