lsp: support the organizeImports code action about templ HOT 4 CLOSED

From my basic understanding I think this will involve supporting "codeActionLiteralSupport", this allows actual page edits to be returned from the textDocument/codeAction request.

After some more investigation, this is nothing to do with the above! The problem is that gopls does not do organizeImports on generated files, the string at the top of our go files DO NOT EDIT means that it is ignoring the request.

I tried removing it in our cached version of the go file, however it seems that gopls is still reading the disk version of the file, therefore it still contains the comment.

One solution would be to remove this comment entirely, @a-h do you think that is sensible, as organize imports is a fairly requested feature?

I have now managed to get gopls to respond to the request. However, now when mapping to the templ file the code becomes mangled, it tries to convert it to a multiline import as the generated file contains multiple imports even if the templ file only has one.

The way I can think to do this, is apply the change to the generated imports list, remove the "implicit" imports and then create our own change list for the templ file.
