Update dependency env_logger from 0.6 to 0.10.2

[jimmystewpot]

The env_logger API has changed in recent revisions, bringing up the dependency to a more recent version to make the codebase easier to maintain in the long term.

A test that defaults to ignored has been left to test any future API changes if required; I have left it there just for simple iterative testing, although it could be removed as it's trivial. Otherwise, this shouldn't break anything.

very nice, thanks for the PR!

Ci is failing with

the package `graphql_client_cli` depends on `env_logger`, with features: `anstream` but `env_logger` does not have these features.
 It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

I don't have the bandwidth to check right now, but it should be straightforward to fix.

@tomhoule, thanks for looking at this pr so quickly. I have not been checking the MSRV information on packages, so this one slipped through the net.

The problem with CI is caused by the minimum version for graphql-client 1.64 vs. a style (via env_logger), which is 1.71. I reverted the env_logger to 0.10.2, which is the last version that supports 1.64. I started working on this update to make cross-platform terminal colours less buggy. I've now reverted the code back to pre-change and left only the dependency update in place (to 0.10.2)

Should the minimum version of rust supported by graphql-client by bumped to something more recent? (This is a supplementary question)

In Summary, the version has gone from 0.6 to 0.10.2 for env_logger; I've updated the subject/title of the PR to reflect the difference. I've also removed the tests.

Absolutely. I'm going to cut a release very soon, and we can make a few breaking changes, including bumping the MSRV right after that.
