[Bug]: CRE CLI download fails

[PatrickAlphaC]

Describe the bug

On a Ubuntu linux machine, running the CRE install script fails:

$ curl -sSL https://cre.chain.link/install.sh | sh
sh: 41: Bad substitution
curl: (23) Failed writing body

If we use bash instead, we get a different error:

$ curl -sSL https://cre.chain.link/install.sh | bash
Installing cre version v1.0.1 for linux/amd64...
######################################################################## 100.0%
/PATH/.cre/bin/cre: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by /PATH/.cre/bin/cre)
/PATH/.cre/bin/cre: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by /PATH/.cre/bin/cre)
Error: cre installation failed.

I have Ubuntu 22 LTS, so I'm assuming CRE only works with 24?

To Reproduce

1. Get a Ubuntu 22.04.5 LTS
2. Try to install chainlink CRE, you will fail
