Update supported terraform versions, highest is now 1.5.7

[sleenen]

Hi,

what is needed to get support for higher terraform versions?

Is this project still maintained and worked on? (not a lot of commits/merges)

kind regards

Will take a look in time. Unsure when though. Note: Work tends to get done in bursts. Also, will consider PRs. No sweat either way of course.

I can maybe have a look, but I'm pretty new to terraspace, don't know where to look yet and are their tests to run etc?

Im currently using terraspace 2.2.17 with terraform 1.12.0 just fine
