CI: fix version check workflow by url encoding filter in url

[emilylange]

This workflow stated consistently failing roughly one week ago. Unfortunately the Workflow on GitHub has no error logs besides

Error: Process completed with exit code 92.

which isn't particularly helpful.

The issue can, however, be reproduced by simply copying parts of the workflow into a local bash script and executing that.

As it turns out, the issue lays in ?filter=fraction>=0.5 when using curl due to missing url encoding.

# curl 'https://versionhistory.googleapis.com/v1/chrome/platforms/linux/channels/stable/versions/all/releases?filter=fraction>=0.5'
curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)

vs

# curl -s 'https://versionhistory.googleapis.com/v1/chrome/platforms/linux/channels/stable/versions/all/releases?filter=fraction%3E=0.5' | wc -l
3128

What is the purpose of "?filter=fraction>=0.5" ? For me it serves exactly identical output with or without this query string.

@joopbraak this allows us to ignore early stable releases, see #2508

Ah, ok, thanks.
