Test with new julia LTS 1.10

[maxstb]

Github actions are running with the new API (#46) and new secrets.
For the secrets however it's important to store it in the following way:
CDSAPI_URL = "url: https://cds.climate.copernicus.eu/api"
CDSAPI_KEY = "key: XXXXXXXXXXXXXXXXXXXXX"

I just considered that we should update the tests to the new LTS version of julia

Fix #46

[maxstb]

Just changed the secret usage to only store the values in github instead of the key-value-pair

@juliohm can you check the secrets again?
CDSAPI_URL = "https://cds.climate.copernicus.eu/api"
CDSAPI_KEY = "XXXXXXXXXXXXXXXXXXXXX"
They should look like this. The CI in my fork runs fine with this setup

Suggested change

	- '1.10'
	- 'lts'

[juliohm]

The keys are in the expected format, without the prefix. I've made the LTS support explicit in the CI.yml.

[juliohm]

I can't propose changes in this branch of your fork, but I am assuming that CI will succeed after you accept the suggestion.

Tried these changes on the master branch. Let's see if they solve the issue.

Issue fixed on master ❤️ Thank you @maxstb
