fix-kubectl - updated tool versions
foreach-secret - a tool to export an ix-app's secret, executing a
command line on the content.

Was created to periodically update AdGuard Home HTTPS certificate over
SSH.

show-console - designed to be executed with `watch`:
    `sudo watch ./show-console.sh'

Will output what is shown on the console.
