Bump intl from 0.20.2 to 0.20.3

[dependabot]

Bumps intl from 0.20.2 to 0.20.3.

Release notes

Sourced from intl's releases.

package:intl v0.20.3

• Updated the Turkish Lira (TRY) currency symbol in simpleCurrencySymbols from "TL" to "₺" (U+20BA). This ensures accuracy and alignment with the official symbol introduced in 2012.
• Fix parsing of locale strings containing script codes in verifiedLocale. For example, zh-Hans-CN would have been previously parsed as zh, but is now parsed as zh_CN.
• Update the Ghanaian Cedis (GHS) currency symbol in simpleCurrencySymbols from "GHS" to "GH₵(U+20B5)".
• Update to CLDR v48.
• Add @pragma('wasm:prefer-inline') to Intl methods that already have @pragma('vm:prefer-inline'), for the same reason: to help omit message descriptions from compiled output.
• Update analysis to newest package:lints.
