entrypoint.sh creates unusable TAR_FILE variable for knope versions >= 0.4.0 and <= 0.7.1

[jselig-rigetti]

See:

action/entrypoint.sh

Line 27 in 407e9ef

TAR_FILE=$(ls knope-*.tgz)

Latest release affected: https://github.com/knope-dev/knope/releases/tag/v0.7.1
Earliest release affected: https://github.com/knope-dev/knope/releases/tag/v0.4.0

Because affected releases have two linux assets, you get an error like the following:

tar: knope-x86_64-unknown-linux-gnu-v0.7.0.tgz\nknope-x86_64-unknown-linux-musl-v0.7.0.tgz:

Cannot open: No such file or directory
