migration: Add for editor::GoToHunk and editor::GoToPrevHunk actions (#26017)

We modified few actions in
https://github.com/zed-industries/zed/pull/25846, which are:

`"editor::GoToHunk" -> ["editor::GoToHunk", { "center_cursor": true }]`
`"editor::GoToPrevHunk" -> ["editor::GoToPrevHunk", { "center_cursor":
true }]`

Also, recently we changed and added migration for:

`["editor::GoToPrevHunk", { "center_cursor": true }] ->
["editor::GoToPreviousHunk", { "center_cursor": true }] `

This means:

1. User that might still have `editor::GoToHunk` won't be automatically
migrated to `["editor::GoToHunk", { "center_cursor": true }]`. Note
value of `center_cursor` is false, in first case (default), and true in
second case.

2. User that might still have `editor::GoToPrevHunk` won't be
automatically migrated to `["editor::GoToPreviousHunk", {
"center_cursor": true }]`. Note, `editor::GoToPrevHunk` is renamed
since, it is now invalid action.

This PR adds those migrations.
