Make curl in install scripts show errors and exit with non-zero status (#150)

Only `-f` and `-S` are new.

Both these new flags could potentially have surfaced an underlying issue
in databricks/cli#2307.

With this change, all curl invocations in this repo use the same set of flags.

Description:

* `-f` / `--fail`
Silently fails on HTTP errors (e.g., 404, 500). Prevents output of error
pages to stdout/stderr, returning exit code 22 instead. Critical for
scripting to avoid processing invalid responses.

* `-s` / `--silent`
Suppresses progress meters, error messages, and other non-essential
output. Ensures clean output for piping or saving to files.

* `-S` / `--show-error`
Overrides -s to display errors if they occur. Balances silent operation
with actionable error reporting.

* `-L` / `--location`
Follows HTTP redirects (3xx responses). Essential for URLs that point to
mirrored or updated resources (e.g., download links that redirect to
CDNs).
