Rebuild MesloLGS NF with newer icons

[romkatv]

New icons have been added to Nerd Fonts since the last time MesloLGS NF has been built. MesloLGS NF needs to be rebuilt to include them.

See #2033, #2167, #2184, #2216.

My plan is as follows.

1. Add POWERLEVEL9K_MODE=nerdfont-v3. Under this mode Material icons will come from F0001-F19C3 rather than from F500-FD46.
2. Add an extra question to the wizard that checks whether F0001-F19C3 contains material icons. More specifically, replace the Debian Logo question (a part of Font Logos (Font Linux), mapped at F300-F31C in Nerd Fonts) with another question that utilizes a Material icon. A good candidate is Arrow Right Bold: U+FC32 nf-mdi-arrow_right_bold in the old range, and U+F0734 nf-md-arrow_right_bold in the new range. Ask about the latter first. If the user replies in the negative, ask about the former.
3. Optional. Rebuild MesloLGS NF based on v2.3.3 of Nerd Fonts. Set Font Version to "1.210;Nerd Fonts 2.3.3".
4. Wait for Nerd Fonts to release v3 and then Rebuild MesloLGS NF based on it.

An alternative to 3 & 4 is to rebuild MesloLGS NF based on v2.3.3 of Nerd Fonts without overriding the source font at F500-FD46. In other words, do now what Nerd Fonts promises to do with v3.

I'm working on steps 1-2. I haven't yet decided how to proceed after that.

The following command can be used to find all icons between U+F500 and U+FD46 used by powerlevel10k:

% git ls-files | xargs -- grep -iE '\\u(0*)f[5-9a-f][0-9a-f]{2}[^0-9a-f]'
internal/icons.zsh:        NETWORK_ICON                   '\uF50D'$s             # 
internal/icons.zsh:        AZURE_ICON                     '\uFD03'               # ﴃ
internal/icons.zsh:        GCLOUD_ICON                    '\uF7B7'               # 
internal/icons.zsh:        PACKAGE_ICON                   '\uF8D6'               # 
internal/wizard.zsh:      sub BATTERY_STAGES "'\uf58d\uf579\uf57a\uf57b\uf57c\uf57d\uf57e\uf57f\uf580\uf581\uf578'"

Steps 1 & 2 are done in https://github.com/romkatv/powerlevel10k/tree/nerdfonts-v3. I don't want to merge this branch as-is because it'll imply that users of MesloLGS NF will have to answer "No" to one of the font capability questions, which is bound to cause confusion and complaints. I'm now working on Step 3. If I succeed, I'll merge branch nerdfonts-v3 into master.

Step 3 is done.

If you are already using MesloLGS NF, consider updating your font. The robust way to do it:

1. Uninstall MesloLGS NF.
2. Reboot.
3. Download these four ttf files:
   • MesloLGS NF Regular.ttf
   • MesloLGS NF Bold.ttf
   • MesloLGS NF Italic.ttf
   • MesloLGS NF Bold Italic.ttf
4. Double-click on each file and click "Install".

I've modified the wizard to prefer the legacy Material icons over the new ones because the new icons trigger a bug in Windows Terminal. I've reported it here: microsoft/terminal#15086

@romkatv Seems like there's a typo in the Kubernetes icon.

powerlevel10k/internal/icons.zsh

Line 527 in b474978

KUBERNETES_ICON '\F10FE' # 󱃾

❯ echo -e '\F10FE'
\F10FE
❯ echo -e '\UF10FE'
󱃾

Let me know if this is a valid observation, I'll send a PR to update the icon unicode.

Thanks! Fixed.
