Updated VS Code extensions

[gnikit]

Modern Fortran now supports natively Language Server support (FORTRAN Intellisense), formatting (fprettify and findent)

[certik]

Should we still keep the other links in a section like "Other tools", so that people can discover them?

[gnikit]

I think the "Other tools" section should be kept mostly because VSCode without GitLens for big projects is rough.
The extensions that I would vouch for are:

• GitLens which is crucial IMO
• Remote Development for SSHing into workstations, WSL and spinning up containers

I would consider adding the CMake extension from Microsoft simply because a lot of people might find it useful (I prefer the command line, but to each their own).

I am not familiar with the TOML extension but I suspect it might be useful for fpm dev work

[certik]

If you want, just put the links that you removed in this PR to the "Other Tools" or "Additional Tools" section, and we can merge it.

So I think this is a good place for new VS Code users that want to code in Fortran to start. I believe it should be okay now.

As for the tools I completely removed, unfortunately they don't play well with the main Fortran extension anymore, so I would not recommend anyone to install them alongside Modern Fortran.

These extensions would attempt to do the same thing as Modern Fortran but given that they would have the same "priority" I don't know what would happen.

e.g. Having installed both Modern Fortran >= 3.0.0 and FOTRAN Intellisense would lead to multiple duplicate hover messages. GoTo Definition/Implementations would lead to undefined behaviour and using any of the new fortls arguments in your settings would cause FORTRAN Intellisense to crash.

I think the fprettify extension would also have problems with auto-formatting OnSave which some people have enabled globally (and also the behaviour would be undefined).

the breaking point extension I think it has become redundant for Modern Fortran since 2019 when I added full-blown debugger support.

There is another Fortran extension (I think called fortran) which does not have any of these features so I suspect users would need these extensions to have a IDE-like experience in VSCode, but then again that project has not been updated since 2017, so I would not recommend users to use it.

Thanks for the discussion and feedback everybody. I think we can go ahead and merge.
