Describe your changes

Rename vscode as flyin plugin

1. Better branding name
2. flyin plugin will host multiple interactive interface e.g. jupyter, neovim, so naming as vscode doesn't make sense anymore

Check all the applicable boxes

• I updated the documentation accordingly.
• All new and existing tests passed.
• All commits are signed-off.

End to end tests

from flytekit import task, workflow
from flytekitplugins.flyin import vscode, VscodeConfig, DEFAULT_CODE_SERVER_EXTENSIONS

@task(
    container_image="localhost:30000/flytekit-cache:0.0.1",
    environment={"FLYTE_SDK_LOGGING_LEVEL": "20"}
)
@vscode(

)
def t():
    ...



# this vscode task will be killed within 10 secs
@task(
    container_image="localhost:30000/flytekit-cache:0.0.1",
    environment={"FLYTE_SDK_LOGGING_LEVEL": "20"}
)
@vscode(
    max_idle_seconds=10,
)
def t_short_live():
    ...



# this vscode task will download default extension + vim extension
config_with_vim = VscodeConfig(
    extension_remote_paths=DEFAULT_CODE_SERVER_EXTENSIONS+["https://open-vsx.org/api/vscodevim/vim/1.27.0/file/vscodevim.vim-1.27.0.vsix"]
)

@task(
    container_image="localhost:30000/flytekit-cache:0.0.1",
    environment={"FLYTE_SDK_LOGGING_LEVEL": "20"}
)
@vscode(
    config=config_with_vim
)
def t_vim():
    ...



@workflow
def wf():
    t()
    t_short_live()
    t_vim()

The above code runs as expected
