fix(go): Remove iferr package from jay-babu/mason-null-ls.nvim and WhoIsSethDaniel/mason-tool-installer.nvim lists

[lucazz]

📑 Description

The iferr package install currently fails with the following error msg:

$ go install github.com/koron/iferr@latest
go: github.com/koron/iferr@latest (in github.com/koron/iferr@v0.0.0-20240122035601-9c3e2fbe4bd1): go.mod:3: invalid go version '1.21.5': must match format 1.23
$ 

Until the package maintainer fixes it, we should remove this package from the list to avoid a bad user experience.

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• [ ] Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• [ ] README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• [ ] Proper usage of opts table rather than setting things up with the config function.

We should pin it instead.

I can compile it just fine. Is your go version up to date?

I can reproduce with a go version older than 1.21. User error.
