[BUG] Format executor fails when installed dotnet-format is out of date

[bcallaghan-et]

Describe the bug
The 3rd-party tool dotnet-format recently published an update (5.1.250801). After this update, all of my dotnet lint targets started failing with the following error

Cannot add package. Manifest file already contains version 5.1.225507 of the package dotnet-format. Uninstall/install or edit manifest file C:\Users\bcallaghan\Source\Repos\etogy-workspace\.config\dotnet-tools.json to specify the new version 5.1.250801.

To Reproduce

1. Specify an older version of dotnet-format in the dotnet-tools.json manifest file (e.g. 5.1.225507)
2. Run the lint target of a dotnet project (e.g. nx lint my-dotnet-proj)

Expected behavior
The executor should properly handle out-of-date versions so that the lint target can still run.

Environment:

• OS: Windows
• Version: 0.11.0

Additional context
The error is directly caused by the redundant tool install before running dotnet-format. One possible strategy for handling out-of-date versions is to update to the latest version each time. Another possible strategy is to lock-in to a specific version (as Nx does with Angular) and avoid re-installing the tool after that.

Hey Ben, this is similar to #179, but has a different root cause. They should probably be handled in the same PR.

Do you want to work on this? I'll assign it to you if so. Otherwise, I can take a look at this sometime this weekend.

I can work on it this week. Which version strategy do you want to go with?

[AgentEnder]

It should go something like this:

If already specified in json file, leave as is. (user can update there tools file to update)
If not, install latest.

Make sure to take a look at #179, as in .NET SDK 6+ we don't want to install the tool at all as it is part of the .NET SDK itself, unfortunately they also decided it was worth changing the --check argument so the syntax is different.

I'm not sure if you are participating in Hacktoberfest at all, but it holds a soft spot in my heart. This repo's participating so if you want the free shirt and stuff you'll be at least a quarter of the way there 😋
