Suggestion - quick action to expand dependency specification in Cargo.toml

When adding dependencies to my Cargo.toml, it’s handy that the latest version is provided as a completion. However, it’s still a bit annoying to type out the dependency specifications when the dependency needs to be configured with additional options, like default_features = false or features = [ "serde" ]. It would be handy to have an action that expands the shorter syntax to the full syntax, placing the cursor before the closing bracket so additional options can be added - replacing serde = "1.0" with serde = { version = "1.0" }

Intentions

• Expand key-value specification into inline table (#6960)
• Extract inline table to separate table (#7003)
• Move separate dependency table into inline table
• Simplify separate table/inline table into key-value if there is only version key (#7559)

@Kobzol actually, I already have a prototype of this feature so I don’t think we should make it twice I’ll try to finish it soon

It might be nice to be able to cycle through the three (only?) main ways of representing them:

rusqlite = "0.24.2"

rusqlite = { version = "0.24.2" }

[dependencies.rusqlite]
version = "0.24.2"
