Double installation Swift 6

[ivan-gaydamakin]

Describe the bug
After upgrade to the last version of mise (v2024.12.0), it tried to install swif 6, but it's already installed by Xcode 16.

On version export v2024.11.29

To Reproduce
Upgrade to last mise version (v2024.12.0)
Create in folder file: .mise.toml with content:

[tools]
swiftlint = '0.55.1'
swiftformat = '0.54.3'
swiftgen = '6.6.3'
tuist = '4.33.0'

and use mise install.

Expected behavior
Do not install swift 6 if it's already installed by Xcode 16.

I guess that happened by that PR:
#3271

[jdx]

toolset:
  asdf:swiftformat@0.54.3
  asdf:swiftgen@6.6.3
  asdf:swiftlint@0.55.1
  asdf:tuist@4.33.0
  core:swift@6.0        (missing)

you've told mise to install swift@6.0

[ivan-gaydamakin]

I didn't do that, only if some dependencies do that.

~/Workspace/app-ios/.mise.toml

[tools]
swiftlint = '0.55.1'
swiftformat = '0.54.3'
swiftgen = '6.6.3'
tuist = '4.33.0'

~/Workspace/app-ios/.swift-version:

6.0

hm, I guess it happened because I have that file. We used .swift-version for swiftormat, can I ignore that file for mise?
