fix: Override Brotli compress default options

[zharinov]

Changes

• BROTLI_PARAM_QUALITY could be a number from 0 to 11. By default, it's 11, and it's slow. I've found 8 is an optimal value which does decent compression and performs well enough.
• According to docs BROTLI_MODE_TEXT is adjusted for UTF-8 text, so let's set it as well.

These changes will significantly speed up the compressing phase, while decompressing speed remains the same.

Context

• Ref: feat: SQLite-based package cache #26608

Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please select one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or
• No unit tests but ran on a real repository, or
• Both unit tests + ran on a real repository
