[Bug 2000551] [NEW] [System Fonts] Replace default sinhala font from LKLUG to Noto

[Aurora]

Public bug reported:

**What's the problem?**

Currently ubuntu comes with LKLUG font for sinhala (si). it's not clear.
e.g. we cannot recognize vowel signs and read websites using that font.
We can change it manually but such changes do not apply to some
applications or application types e.g. snap apps etc.

LKLUG (last active: 2012) no one maintain it now.

**What expected to happen?**

We would like to see Noto serif sinhala as the default font for sinhala language
https://fonts.google.com/noto/specimen/Noto+Serif+Sinhala
[Highlighs: clear (readable), thin, takes less space than sans sinhala]

If noto sans is more suitable for ubuntuOS, you can add noto sans sinhala https://fonts.google.com/noto/specimen/Noto+Sans+Sinhala
[Highlighs: clear (readable), thick, takes more space than serif sinhala]

**Additional details**

Screenshots (see the difference: LKLUG/Noto)

Also, some developers already have designed tools, scripts for that problem however many people do not try to find these scripts and switch to other OS

Please review details, screenshots and posts. This is not a personal
opinion and atleast, i expect to see this change in the next interim or
LTS release.

Furthermore, please let me know if i can help to speed-up this
replacement process
