Don't create a bundle for versions older than FAIR supports

[johnbillion]

The bundles created for the release bundle FAIR with every version of WordPress back to 4.7, but FAIR only supports 5.4 and higher.

This adjusts the bundle script so it skips bundles for unsupported versions of WordPress, and fixes a path issue which was preventing rsync from running on my macOS machine.

Steps to test:

1. Run ./bin/bundle.sh
2. Confirm the output shows that older versions were skipped:

Skipping 5.3.20 (older than 5.4)
Skipping 5.2.23 (older than 5.4)
Skipping 5.1.21 (older than 5.4)
Skipping 5.0.24 (older than 5.4)
Skipping 4.9.28 (older than 5.4)
Skipping 4.8.27 (older than 5.4)
Skipping 4.7.31 (older than 5.4)

A question unrelated to this pull request -- what's the reason for creating all these releases? It definitely made me think before downloading the release for install. I'm wondering how users would know which version to pick? That information isn't part of the release notes or in the README.

p.s. happy to open an issue if we want to discuss that in isolation.

I'm wondering how users would know which version to pick?

Hopefully the users aren't using Github, but the answer is the one named fair-plugin*

The others (with wordpress) are installers for WP core with our plugin auto-added (like Akismet or Hello Dolly)

@rmccue I'm flagging this for the 1.2 release - I do think there's a point we don't need to build things we can't support :D

I believe the current instructions are to download the plugin from GitHub releases:

fair-plugin/README.md

Lines 15 to 17 in 4be6646

	FAIR can be installed manually by downloading the latest zip from releases and install it via your WordPress admin dashboard.
	* [FAIR Releases](https://github.com/fairpm/fair-plugin/releases)

https://github.com/fairpm/.github/blob/734cf38798dc9eeb8bdab1cba38ddbcd37bd48de/profile/README.md?plain=1#L9-L10

So I did that and was really overwhelmed with the amount of ZIPs I saw there 😅

All instances of "Install Plugin" appear to link to the GitHub releases:

• https://fair.pm/packages/

Tested locally and it works great!

Separate from this PR, to facilitate testing in different setups, we should probably remove the hardcoded assumed temporary directory in favour of $TMPDIR with a fallback to /tmp if the variable isn't defined. At the least, we should use the script's $DIST_DIR variable consistently instead of /tmp/fair-dist.
