[bug]: checkLatestRelease() fails when GitHub API returns compact JSON

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

This is related to #6162 which addressed a similar issue in checkLatestRelease() but did not fix the root cause.

The checkLatestRelease() function in deployments/cli/community/install.sh uses grep to extract the tag_name from the GitHub API response:

grep -o '"tag_name": "[^"]*"'

This assumes a space after the colon ("tag_name": "v1.2.3"), but the GitHub API sometimes returns compact JSON without spaces ("tag_name":"v1.2.3"), causing grep to match nothing and the upgrade to fail with:

Failed to check for the latest release. Exiting...

Fix: Replace the grep | sed pipeline with python3 which is available on all supported systems:

local latest_release=$(curl -sSL https://api.github.com/repos/$GH_REPO/releases/latest | python3 -c "import sys,json; print(json.load(sys.stdin)['tag_name'])")

Affected: setup.sh Option 5 (Upgrade)

Steps to reproduce

1. Run ./setup.sh
2. Select Option 5 (Upgrade)
3. Script calls checkLatestRelease() which calls the GitHub API
4. GitHub API returns compact JSON without spaces after colons
5. grep -o '"tag_name": "[^"]*"' matches nothing
6. Script exits with "Failed to check for the latest release. Exiting..."
