🚀 Feature Request

Description

Launchpad supported languages have been updated recently on Apr 12.

Describe the solution you'd like

2 weeks prior Prysm enhanced its web backend ,Part of #8664 , by supporting bip39 Mnemonic language in recovering their wallet from a mnemonic.
Currently supported languages in Bip39 are: English, chinese_simplified, chinese_traditional , French, Italian , Japanese , Korean, Spanish

New list: Chinses simplified, Czech, English, Italian, Korean, Spanish, French , Greek, Indonesian, Portuguese, Romanian, Arabic, German, Japanese, Turkish.

Both the CLI and web have to be up-to-date with the Launchpad language support.

Describe alternatives you've considered

None. Maintain the status quo.

If the Prysm team approves the feature I can take this one.

@ahadda5 Assigned :)

[ahadda5]

Well the Launchpad list set is inclusive of the bip39 except the Chinese(simplified vs traditional). Should we maintain traditional? I know @rauljordan has Chinese knowledge so maybe he can help?

[rauljordan]

Yes we should maintain traditional @ahadda5 as they have a different corpus and the characters are different

[ahadda5]

We are limited with what bip39 offers. Portuguese can be added to the go library. Tracking this issue
For now Czech is missing from Prysm.
