Add support for armv6l architecture in install script for Raspberry Pi Zero

[kou029w]

Environment

• Device: Raspberry Pi Zero
• Operating System: Linux 6.6.31+rpi-rpi-v6
• Architecture: armv6l

Issue

The install script https://webinstall.dev/api/installers/node@lts.sh fails to execute on Raspberry Pi Zero due to an invalid architecture value derived from the User-Agent string.

Example User-Agent string: Linux/6.6.31+rpi-rpi-v6 armv6l/unknown gnu

### https://github.com/webinstall/webi-installers/blob/5c12cb1fa7f01c851de912344a9d29e288ce6215/webi/webi.sh#L77C1-L86C1
$ echo $WEBI_UA
Linux/6.6.31+rpi-rpi-v6 armv6l/unknown gnu

Changes

Updated the architecture detection map to include armv6l.

@kou029w Sorry I didn't see this until today. It's up on https://beta.webinstall.dev.

Will you test it out?

Thanks for the update!
I tested it on a Raspberry Pi Zero and everything worked as expected!

pi@raspberrypi:~ $ curl -sS https://beta.webi.sh/node | sh

Very nice use of <details><summary>. A+.

I'm batching some other changes and this will go live with those in prod today.

Also: I'd be curious to know if the armv7l builds run on the Pi Zero.

I believe that many of the armv6l CPUs will actually run armv7l binaries (but not armv7a).

The armv7l binary does not seem to be compatible with the Raspberry Pi Zero, as it results in an Illegal instruction error. (It might work with the Raspberry Pi Zero 2, though.)

pi@raspberrypi:~ $ ./node-v20.17.0-linux-armv7l/bin/node -v
Illegal instruction
