Update a required Neovim version to v0.9.0+

[lewart]

The README.md file currently states that fidget requires Neovim 0.8.0+, but this is incorrect for versions starting from v0.0.0.

When I try to run a fidget v0.0.0 or newer in a Neovim 0.8.3, it fails with error

Error executing vim.schedule lua callback: vim/shared.lua:0: plain: expected boolean, got table
stack traceback:
        [C]: in function 'error'
        vim/shared.lua: in function 'validate'
        vim/shared.lua: in function 'gsplit'
        ...e/nvim/lazy/fidget.nvim/lua/fidget/notification/view.lua:163: in function 'render_item'

A gsplit function accepts a table type parameter since Neovim 0.9.0.

Please correct a required version in a READMEmd file to v0.9.0+.

P.S.
It would be useful to see an information about changed required Neovim version in release-notes of fidget v0.0.0.

Oof, thanks for catching that. I should have been more thorough with testing.

It would be useful to see an information about changed required Neovim version in release-notes of fidget v0.0.0.

For this, do you mean backporting this documentation change onto all past versions, and then retagging everything? Or just editing the notes here: https://github.com/j-hui/fidget.nvim/releases

Thank you for your time!

I meant just editing a release note https://github.com/j-hui/fidget.nvim/releases/tag/v0.0.0.

No problem! It's fixed.
