Drop pcre2-version-update.patch

[Thorsten]

The pcre2-version-update.patch in disco should not be necessary anymore and should be removed, since pcre2 has been accepted in main [0] and vte has been build with pcre2 support [1]. Moreover, the pcre2 backport in vte caused various confusion [2] and other issues [3].

Status changed to 'Confirmed' because the bug affects multiple users.

Why do you think the patch is still in tilix in Ubuntu 19.04?

I believe I dropped the patch in January when I prepared 1.8.9-1.

[Egmont Koblinger (egmont-gmail)]

The patch itself is misleadingly still present inside tilix_1.8.9-1build1.debian.tar.xz. It's not mentioned in 'series' though, which I believe means it's not applied? This might have confused OP and me as well.

[Thorsten (thorstenr-42)]

Ah sry, i missed the series file/thought it was still applied
