bug#45358: bootstrap fails due to a certificate mismatch

[Grigoriy Sokolik]

The temporary workaround could be, at least to skip the certificate
validation:

```
$ git --no-pager diff
diff --git a/bootstrap b/bootstrap
index 7523f65b4..dcb8aa388 100755
--- a/bootstrap
+++ b/bootstrap
@@ -180,7 +180,7 @@ bootstrap_epilogue() { :; }
 # specified directory.  Fill in the first %s with the destination
 # directory and the second with the domain name.
 po_download_command_format=\
-"wget --mirror --level=1 -nd -nv -A.po -P '%s' \
+"wget --mirror --level=1 -nd --no-check-certificate -nv -A.po -P '%s' \
  https://translationproject.org/latest/%s/";

 # Prefer a non-empty tarname (4th argument of AC_INIT if given), else
```

But be careful, this is really bad advice: fetching anything without
consistency ad authority validation is really insecure!

Thanks!
