and weird behavior

• fnm install --lts did not auto add lts-latest alias. but --lts semantics indicates lts-latest
• fnm default 20, default and lts-latest is added
• fnm default lts-default, removes default and lts-default

expected behavior:

• fnm install --lts can auto add lts-latest
• fnm default lts-latest or a --lts flag can set default to lts latest and UPDATEABLE (which means when a lts update installed, default is point to new lts)
