[bug] tauri-cli build fails projects with workspace license field

[anatawa12]

Describe the bug

tauri-cli build fails projects with workspace license field.

I found this bug during testing #

It looks 253595a adds license to the CargoPackageSettings but it does not accept license.workspace.

> cargo tauri build
       Error failed to load cargo settings: failed to parse Cargo.toml: TOML parse error at line 8, column 1
  |
8 | license.workspace = true
  | ^^^^^^^
invalid type: map, expected a string

Reproduction

create empty tauri project with workspace and set license.workspace = true

Expected behavior

license.workspace = true does not cause error

Full tauri info output
