Add speculative_enabled argument to tfe_workspace

[jgiannuzzi]

Description

• Requires a go-tfe release with Add SpeculativeEnabled attribute to workspace go-tfe#132 -> go-tfe v0.10.2 has been released

This change adds support for the speculative_enabled argument to tfe_workspace.

Fixes #211

Testing plan

The tests have been updated to test this in the same way that file_triggers_enabled is tested.
file_triggers_enabled also defaults to true during workspace creation and is thus quite comparable.

Hey @koikonom, I had to force push my commit to bump go-tfe to v0.10.2. I did the update on Linux so that the vendor dir would not dramatically change.

This PR is now ready for review! 😄

[koikonom]

Yeah you had to force push because I pushed the same change myself :)

[jgiannuzzi]

Thanks for the merge, @koikonom!

Hey @koikonom, we would love to be able to use this new feature in an official build — could you please create a new release soon? Thanks! 🙏
