Fix IndexError when there are no suggestions

[elliotwutingfeng]

When there are no suggestions returned by suggest_product() we get an IndexError from attempting to read the first element of an empty list.

I changed it such that if there are no suggestions, no [Y/n] option will be given; the prompt will only state that the search term is not found and exit immediately.

Before

$ eol julia
Traceback (most recent call last):
  File "/home/tingfeng/miniconda3/bin/eol", line 8, in <module>
    sys.exit(main())
             ^^^^^^
  File "/home/tingfeng/miniconda3/lib/python3.11/site-packages/norwegianblue/cli.py", line 132, in main
    output = norwegianblue.norwegianblue(
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/tingfeng/miniconda3/lib/python3.11/site-packages/norwegianblue/__init__.py", line 64, in norwegianblue
    suggestion = suggest_product(product)
                 ^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/tingfeng/miniconda3/lib/python3.11/site-packages/norwegianblue/__init__.py", line 107, in suggest_product
    return result[0]
           ~~~~~~^^^
IndexError: list index out of range
$

After

$ eol julia
Product 'julia' not found, run 'eol all' for list.
$

Thanks! Looks good, just one small suggestion about the test.

Hmm, and the other test_norwegianblue_formats failures are also now happening on main, so unrelated to this: https://github.com/hugovk/norwegianblue/actions/runs/7622302693

This one prompts for andro and proceeds to handle centos only if answered with "Y". But if answered with "n" it halts at andro

$ eol bootstrap andro centos

This one always halts at julia.

$ eol bootstrap julia centos

Fixed in #190, let's update this branch.
