Bump devvm timeout creation

We recently had quite a few pipeline failures due to devvm creation timeout

[FAILED] Expected success, but got an error:
      <*fmt.wrapError | 0xc000b06160>: 
      devvm did not become ready: timed out after 38m0s while waiting for booter to set up devvm
      {
          msg: "devvm did not become ready: timed out after 38m0s while waiting for booter to set up devvm",
          err: <*errors.errorString | 0xc0011bab60>{
              s: "timed out after 38m0s while waiting for booter to set up devvm",
          },
      }

Might be worth trying to bump it?
